PKU 3673. Cow Multiplication. [판정:AC]

무식한 문제는 무식한 해결이 답이죠 -_-;

#include <stdio.h> void main() { int board[2][10] = {0}; int a, b; int acol, bcol; int i, j, temp; scanf("%d %d", &a, &b); acol = 0; while( a > 0 ) { board[0][acol] = a % 10; a /= 10; acol++; } bcol = 0; while( b > 0 ) { board[1][bcol] = b % 10; b /= 10; bcol++; } temp = 0; for( i = 0; i < acol; i++ ) { for( j = 0; j < bcol; j++ ) { temp += board[0][i] * board[1][j]; } } printf("%d\n", temp); }
