So, in this case, the pivot element is needed to be found following which the maximum sum can be calculated. Min and Max in a List in Java; Collections min() method in Java with Examples; Finding minimum and maximum element of a Collection in Java; Java Program to Find array sum using Bitwise OR after splitting given array in two halves after K circular shifts.
