What of the following groups on the Home tab contains the command for clearing the contents of a cell?

Answered below

Explanation:

Index of the first element compared to the key is 5. The element itself is 55.

This index is evaluated by the addition of the index of the first element which is 0(zero) and the the index of the last element which is 10.

( Index of the last element is determined by subtracting the one from the total number of elements)

After the addition, the result is divided by 2 to get the first index from which the binary search begins.

firstIndex = 0

lastIndex = array.length - 1

midpoint = (firstIndex + lastIndex) / 2
