#include <stdio.h> int main() { int input, input_first, count, p, pay; while(scanf("%d", &input)) { pay = 0; if (input == 0) { break; } input_first = input; count = 1; p = 1; while(input != 0) { input--; pay += count; if (count == p) { p = 1; count++; } else { p++; } } printf("%d %d\n", input_first, pay); } }
