WebThe following is our sorted array and let us assume that we need to search the location of value 10 using binary search. First, we shall determine half of the array by using this formula −. mid = low + (high - low) / 2. Here it is, 0 + (9 - 0 ) / 2 = 4 (integer value of 4.5). So, 4 is mid of the array. WebMar 4, 2024 · Binary Search (sometimes known as Logarithmic Search) is a widely popular algorithm to search a sorted array for the position of a given element. It works on a divide and conquer basis by comparing the target element with the middle element of the array.
