Interview questions hide clues. This course trains you to spot them, so even new questions feel familiar. Tap a pattern to try it.
“Find if something appeared before, or count how often it appears.”
Hashing
A hash map remembers everything you have seen, in one pass.
Two Sum, Valid Anagram, Group Anagrams
“A sorted array, and you need a pair or triplet that fits a rule.”
Two pointers
Move two markers towards each other instead of checking every pair.
3Sum, Container With Most Water
“The longest or shortest substring or subarray that follows a rule.”
Sliding window
Grow and shrink one window instead of starting over each time.
Longest Substring Without Repeating Characters, Minimum Window Substring
“Sorted data, even rotated, and you must find something fast.”
Binary search
Cut the search space in half at every step.
Binary search on sorted and rotated arrays
“A linked list that might loop, or you need its middle.”
Fast and slow pointers
One pointer moves twice as fast, so the loop reveals itself.
Linked List Cycle, Middle of the Linked List
“Count the ways, or find the best answer, built from smaller answers.”
Dynamic programming
Save answers to small problems so you never solve them twice.
Classic memoization and tabulation problems
