Procedural Programming Expansion Write a program that reads a sequence of integers (until 0) m1,ni, m2, n2, ..., Mk,n,0 and prints the following m1 + m1+m +m2 +m2t+ m2 mk mktmksum On the left side, m1 is repeated n1-times, m2 is repeated n2-times, and so on. The value on the right side is the value of the expression on the left. Example of input: 5243710 Corresponding output: 5+5+4+4+4+7-29 Example of input: 230 Corresponding output: 2+2+2-6
