WebJul 27, 2024 · In a binary search algorithm, the array taken gets divided by half at every iteration. If n is the length of the array at the first iteration, then at the second iteration, the length of the array will be n/2. Again dividing by half in the third iteration will make the array’s length = (n/2)/2=n/ (2^k). WebJul 4, 2024 · A class named Demo contains the binary search function, that takes the left right and value that needs to be searched. Once the binary search is implemented, a main function creates an instance of the Demo object and assigns values to an array. This binary search function is called on the array by passing a specific value to search as a parameter.
