How Do You Search an Array in Binary

Binary search begins by comparing an element in the middle of the array with the target value. If the target value matches the element, its position in the array is returned. If the target value is less than the element, the search continues in the lower half of the array.

What is the formula for binary search?

In a binary search algorithm, the array taken gets divided by half at every iteration. Again dividing by half in the third iteration will make the array’s length = (n/2)/2=n/(2^k). Similarly, at the fourth iteration, the value of the array’s length will be n/(2^3).

What are the steps of binary search?

• Step 1 – Read the search element from the user.
• Step 2 – Find the middle element in the sorted list.
• Step 3 – Compare the search element with the middle element in the sorted list.
• Step 4 – If both are matched, then display “Given element is found!!!” and terminate the function.
