Like all divide-and-conquer algorithms, binary search first divides a large array into two smaller subarrays and then recursively (or iteratively) operate the subarrays. But instead of working on both subarrays, it discards one subarray and continues on the second subarray.

WebJun 22, 2024 · A simple approach is to do a linear search, i.e Start from the leftmost element of arr [] and one by one compare x with each element of arr [] If x matches with an element, return the index.
