/* ALGORITHM:

1.	Declare the variables in any programming language
2.	initialize sum=0;
3.	Enter the no of elements
4.	Enter the elements values
5.	Found the sum by using loop in array and update sum value in which loop must be continue till (no of elements-1 ) times
6.	avg=sum/no of elements
7.	Find the Largest element by checking with temporary element.
8.	Print the values of sum and largest element
