Can you solve this real interview question? Find the Kth Smallest Sum of a Matrix With Sorted Rows - You are given an m x n matrix mat that has its rows sorted in non-decreasing order and an integer k. You are allowed to choose exactly one element from
Can you solve this real interview question? Find Kth Bit in Nth Binary String - Given two positive integers n and k, the binary string Sn is formed as follows: * S1 = "0" * Si = Si - 1 + "1" + reverse(invert(Si - 1)) for i > 1 Where + denotes the con
