WebApr 29, 2024 · Implementation: Python has built-in binary search functions for both sides: bisect_left() and bisect_right(). The built-in function for Java, Arrays.binarySearch() does not find the left-most insertion point, so it's easier to define our own binary search function. C++ can use the built-in function equal_range(), which returns iterator pointers to the range of … WebApr 11, 2024 · You are given a sorted array ARR consisting of N integers and an integer X. You need to find the first and last position of occurrence of X in the array. Note: 1. The array follows 0-based indexing, so you need to return 0-based indices. 2. If X is not present in the array, return “-1 -1”. 3.
