WebCan you solve this real interview question? Search a 2D Matrix - You are given an m x n integer matrix matrix with the following two properties: * Each row is sorted in non-decreasing order. * The first integer of each row is greater than the last integer of the previous row. Given an integer target, return true if target is in matrix or false otherwise. WebBinary Search - Given an array of integers nums which is sorted in ascending order, and an integer target, write a function to search target in nums. If target exists, then return its index. Otherwise, return -1. You must write an algorithm with O(log n) runtime complexity. Input: nums = [-1,0,3,5,9,12], target = 9 Output: 4
