Sorting Algorithms – Quick Reference

Algorithm	Concise Definition	Core Characteristics	Typical Use‑Cases
Bubble Sort	Repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order; each pass “bubbles” the largest unsorted element to its final position.	• Time Complexity – Best: O(n) (already sorted, with early‑exit flag) • Worst / Average: O(n²) • Space Complexity – O(1) (in‑place) • Stability – Stable • Adaptive – Yes (detects sorted list) • Simple to implement; no recursion or extra data structures.	Educational demos, tiny datasets (< ~20 items), situations where code size matters more than speed.
Merge Sort	A divide‑and‑conquer algorithm that recursively splits the array into halves, sorts each half, and then merges the two sorted halves into a single sorted list.	• Time Complexity – Best / Avg / Worst: O(n log n) • Space Complexity – O(n) auxiliary (classic top‑down) or O(log n) extra for in‑place variants (more complex) • Stability – Stable (as long as merge step preserves order) • Parallelizable – Yes, each half can be sorted independently. • Predictable performance; not affected by input order.	Large datasets that fit in external storage (external‑merge sort), linked lists, situations demanding guaranteed O(n log n) time and stability.
Quick Sort	A divide‑and‑conquer algorithm that selects a “pivot”, partitions the array into elements < pivot and > pivot, then recursively sorts the two partitions.	• Time Complexity – Best / Avg: O(n log n) • Worst‑case: O(n²) (rare with good pivot strategy) • Space Complexity – O(log n) average (due to recursion depth) ; in‑place (no extra arrays) • Stability – Not stable (unless specially modified) • Cache‑friendly – Works well with contiguous memory, low constant factors. • Pivot selection strategies (random, median‑of‑three, introsort) greatly affect robustness.	General‑purpose sorting in memory‑resident arrays, especially when average‑case speed matters more than worst‑case guarantees. Used in standard libraries (often with introsort fallback).

Quick‑look Summary

Algorithm	O(n log n) Guarantee?	In‑place?	Stable?	Typical Complexity
Bubble Sort	No (O(n²) worst)	Yes	Yes	O(n²) average
Merge Sort	Yes (always)	No (needs extra array)	Yes	O(n log n)
Quick Sort	Usually (average)	Yes	No (default)	O(n log n) avg, O(n²) worst

How to Choose?

Very small or already‑sorted data → Bubble sort (or insertion sort) is fine.
Need guaranteed O(n log n) & stability → Merge sort (or stable variants of quicksort).
Need fast average performance & low memory overhead → Quick sort (with a good pivot rule or fall‑back to heap/merge sort via introsort).

What a Hash Table Is

A hash table (also called a hash map or dictionary) is a data structure that stores key‑value pairs and lets you:

Operation	Expected time (average)
Insert	O(1)
Lookup	O(1)
Delete	O(1)

These constant‑time guarantees come from two ideas:

Hashing – a deterministic function that maps a key to an index in a fixed‑size array.
Collision handling – a strategy for dealing with the inevitable case where two different keys map to the same index.

Below is a step‑by‑step walk‑through of the internal mechanics of a typical hash table implementation.

1. Core Components

Component	Description
Table (bucket array)	A contiguous array `T[0 … m‑1]`. Each slot is called a bucket. `m` is the capacity (number of buckets).
Hash function `h(k)`	Takes a key `k` and returns an integer in `[0, m‑1]`. Usually `h(k) = (hashCode(k) mod m)`. The raw `hashCode` is often produced by the language’s built‑in hash algorithm.
Collision‑resolution structure	Either a linked list (separate chaining) or a probe sequence (open addressing).
Size `n`	Number of stored key‑value pairs.
Load factor `α = n / m`	Controls when the table is resized. Common thresholds: 0.75 for chaining, 0.5‑0.7 for open addressing.

2. Insertion (Separate Chaining)

function put(key, value):
    idx = h(key)                     // compute bucket index
    bucket = T[idx]                  // bucket is a linked list (or dynamic array)

Sorting Algorithms – Quick Reference

Algorithm	Concise Definition	Core Characteristics	Typical Use‑Cases
Bubble Sort	Repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order; each pass “bubbles” the largest unsorted element to its final position.	• Time Complexity – Best: O(n) (already sorted, with early‑exit flag) • Worst / Average: O(n²) • Space Complexity – O(1) (in‑place) • Stability – Stable • Adaptive – Yes (detects sorted list) • Simple to implement; no recursion or extra data structures.	Educational demos, tiny datasets (< ~20 items), situations where code size matters more than speed.
Merge Sort	A divide‑and‑conquer algorithm that recursively splits the array into halves, sorts each half, and then merges the two sorted halves into a single sorted list.	• Time Complexity – Best / Avg / Worst: O(n log n) • Space Complexity – O(n) auxiliary (classic top‑down) or O(log n) extra for in‑place variants (more complex) • Stability – Stable (as long as merge step preserves order) • Parallelizable – Yes, each half can be sorted independently. • Predictable performance; not affected by input order.	Large datasets that fit in external storage (external‑merge sort), linked lists, situations demanding guaranteed O(n log n) time and stability.
Quick Sort	A divide‑and‑conquer algorithm that selects a “pivot”, partitions the array into elements < pivot and > pivot, then recursively sorts the two partitions.	• Time Complexity – Best / Avg: O(n log n) • Worst‑case: O(n²) (rare with good pivot strategy) • Space Complexity – O(log n) average (due to recursion depth) ; in‑place (no extra arrays) • Stability – Not stable (unless specially modified) • Cache‑friendly – Works well with contiguous memory, low constant factors. • Pivot selection strategies (random, median‑of‑three, introsort) greatly affect robustness.	General‑purpose sorting in memory‑resident arrays, especially when average‑case speed matters more than worst‑case guarantees. Used in standard libraries (often with introsort fallback).

Quick‑look Summary

Algorithm	O(n log n) Guarantee?	In‑place?	Stable?	Typical Complexity
Bubble Sort	No (O(n²) worst)	Yes	Yes	O(n²) average
Merge Sort	Yes (always)	No (needs extra array)	Yes	O(n log n)
Quick Sort	Usually (average)	Yes	No (default)	O(n log n) avg, O(n²) worst

How to Choose?

Very small or already‑sorted data → Bubble sort (or insertion sort) is fine.
Need guaranteed O(n log n) & stability → Merge sort (or stable variants of quicksort).
Need fast average performance & low memory overhead → Quick sort (with a good pivot rule or fall‑back to heap/merge sort via introsort).

What a Hash Table Is

A hash table (also called a hash map or dictionary) is a data structure that stores key‑value pairs and lets you:

Operation	Expected time (average)
Insert	O(1)
Lookup	O(1)
Delete	O(1)

These constant‑time guarantees come from two ideas:

Hashing – a deterministic function that maps a key to an index in a fixed‑size array.
Collision handling – a strategy for dealing with the inevitable case where two different keys map to the same index.

Below is a step‑by‑step walk‑through of the internal mechanics of a typical hash table implementation.

1. Core Components

Component	Description
Table (bucket array)	A contiguous array `T[0 … m‑1]`. Each slot is called a bucket. `m` is the capacity (number of buckets).
Hash function `h(k)`	Takes a key `k` and returns an integer in `[0, m‑1]`. Usually `h(k) = (hashCode(k) mod m)`. The raw `hashCode` is often produced by the language’s built‑in hash algorithm.
Collision‑resolution structure	Either a linked list (separate chaining) or a probe sequence (open addressing).
Size `n`	Number of stored key‑value pairs.
Load factor `α = n / m`	Controls when the table is resized. Common thresholds: 0.75 for chaining, 0.5‑0.7 for open addressing.

2. Insertion (Separate Chaining)

function put(key, value):
    idx = h(key)                     // compute bucket index
    bucket = T[idx]                  // bucket is a linked list (or dynamic array)
