Interesting numbers

CodeChefOpen on judge ↗

Description If a number n is said to be an interesting number, then while adding n with n + 1 it must not produce any carry. For example n = 5,6,7,8 are non-interesting numbers since they produce the carry. You have given two integers n and x then construct a new integer, s, by repeating n a total of x times. For example n = 51 and x = 3,then s = 515151. Given two inputs n and x, then construct s
