A problem for practicing basic input-output, variables declaration and conditional (if, if-else) statements.
// This website takes input-output from file instead
// of standard input output like most competitive
// programming websites. Hence, here's a skeleton code
// (C++ only) to get you started
#include <cstdio>
#include <iostream>
using namespace std;
int main() {
freopen("INPUT_FILE_NAME.txt", "r", stdin);
freopen("OUTPUT_FILE_NAME.txt", "w", stdout);
/* ... your code here ... */
/* ... cin, cout will work normally. example ... */
/* ... int a, b; cin >> a >> b; ... */
return 0;
}
Feel free to ask questions if you get stuck.
