公式
B - Nutrients 解説 by en_translator
This problem can be solved by appropriate operations on two-dimensional arrays.
Find the total amount of each nutrition and check if all of them exceeds the goal. Beware of indices handling.
Sample code (C)
#include <stdio.h>
int main(){
int n, m;
scanf("%d%d", &n, &m);
int a[100];
for(int i=0; i<m; i++){
scanf("%d", &a[i]);
}
int x[100][100];
for(int i=0; i<n; i++){
for(int j=0; j<m; j++){
scanf("%d", &x[i][j]);
}
}
for(int j=0; j<m; j++){
// 栄養素 j について判定する
int sum = 0;
for(int i=0; i<n; i++){
sum += x[i][j];
}
if(sum < a[j]){
puts("No");
return 0;
}
}
puts("Yes");
}
Sample code (Python)
N, M = map(int,input().split())
A = list(map(int,input().split()))
X = [list(map(int,input().split())) for _ in range(N)]
for j in range(M):
s = 0
for i in range(N):
s += X[i][j]
if s < A[j]:
print("No")
exit()
print("Yes")
