Every data structure is a trade-off against arrays. That's not hyperbole.

data structure O(1) read

Hash Maps — O(1) or Die Trying

If I could bring one data structure to a desert island coding interview, it's this one.

data structure O(1) avg

03

Binary Search — Twenty Comparisons for a Million

The algorithm that makes you feel stupid for ever writing a for loop over sorted data.

pattern O(log n)

04

Sliding Window — Kill the Nested Loop

Turn O(n²) brute force into O(n) by being smarter about what you recompute.

pattern O(n)

05

The simplest useful data structure after arrays. Push, pop, and the patterns they unlock.

data structure LIFO
