SUM OF POWERS:

you are given a list of integers L of size N. write a program to compute the value of SUM

SUM=x1pow1+x2pow2+x3pow3+-----+xNpowN

where xi concatenated with powi is the i th element of the list L and powj is single digit number

input:

The input contains space-separated N integers

Explanation: L=[25]

x1=2 ,pow1=5

SUM=2^5=32

i/p: L=[132,301]

x1=13,pow1=2

x2=30,pow2=1

SUM=13^2 +30^1=199

i/p:25

o/p:32

i/p:132 301

o/p:199
