What is state in DP?
Choose an answer
, 1 The hash map used for memoization. Representation of subproblem (e.g.,
2
index, capacity, cost).
3 The final answer to the problem. 4 The recursive function call stack.

What is the Two Pointer pattern? Technique where two indices traverse a structure
(usually array/string) from different directions or
speeds to reduce time complexity from O(n²) to
O(n). Used in sorted arrays, pair problems, and
partitioning.
When do you use the Sliding When solving problems involving contiguous
Window technique? subarrays or substrings where you track a dynamic
range (e.g., max sum, longest substring). Optimizes
brute force O(n²) to O(n).
What is the Sliding Window template Used when window size is fixed (e.g., max sum of
for fixed size? subarray size k).
