Please Answer in terms of C.

Assume that the function Mystery has been defined as follows:
int Mystery (int n) { int m;
while( n >= 10 ) { m = 0; while( n > 0 ) { m += n % 10; n /= 10; } n = m; } return(n);
}

What is the value of Mystery(2345)?

In words, explain what the Mystery function does.

Answer #1

It will return the sum of given digits until it become single digit

like 2+3+4+5 = 14

1+4=5

so it will return 5
