We keep track of global maximum sum so far and the maximum sum, which include the current element. · When we find global maximum value so far is less than the maximum value containing current value we update the global maximum value. · Finally return the global maximum value.Concept of Stack A stack is a memory in which values are stored and retrieved in “last in firs import java.util.*; class SumOfArray { public static void main(String[] args) { Scanner s=new Scanner(System.in); System.out.println("enter size of Array"); int a=s.nextInt(); int[] arr=new int[a]; System.out.println("enter element of Array"); for(int i=0;i<a;i++) {                 arr[i]=s.nextInt(); }         System.out.println("Max sub...
