WebSteps to perform the binary search in C++ Step 1: Declare the variables and input all elements of an array in sorted order (ascending or descending). Step 2: Divide the lists of array elements into halves. Step 3: Now compare the target elements with the middle element of the array. WebHere is modified pseudocode for binary search that handles the case in which the target number is not present: Let min = 0 and max = n-1. If max < min, then stop: target is not present in array. Return -1. Compute guess as the average of max and min, rounded down (so that it is an integer). If array [guess] equals target, then stop.
