Given two sparse matrices A and B, return the result of AB. You may assume that A’s column number is equal to B’s row number. Example: Input: A = …

Quicksort is the de-factor sorting algorithm that is widely used. Its average runtime complexity is O(nlogn) and it’s usually implemented in either recursion or iterative style. Quicksort can be …

Given an array A of 0s and 1s, consider N_i: the i-th subarray from A to A interpreted as a binary number (from most-significant-bit to least-significant-bit.) Return a list …
