If the value is found before the end of the array, it indicates that the value is present in the array whereas if it encounters the value at the end of the array it means that the value to be searched is not present in the array. The Sentinel Search is usually used in Embedded Systems as you don't need a loop counter to keep track of the location of the loop-iterator within the array.
