Find mid value of low and high using mid = low + (high-low)/2. find the value of mid * mid, if mid * mid == n then return mid value. Repeat from steps 2 to 4 until we find the value.

If the reasonable portion had 32 elements, then an incorrect guess cuts it down to have at most 16. Binary search halves the size of the reasonable portion upon every incorrect guess. optical isomerism save my examsSimply put, the algorithm compares the keyvalue with the middle element of the array; if they are unequal, the half in which the key cannot be part of is eliminated, and the search continues for the remaining half until it succeeds.
