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. You found it! Web1 day ago · Step 1 − Create a function to implement a binary search algorithm. Step 2 − Inside the function, first we find the lower bound and upper bound range of the given array. Step 3 − Run a while loop till LBound<=UBound. Step 4 − Now find the middle value of the given range. And check if the middle value is equal to the key element.
