改用 scanf 進行輸入
我改成scanf,printf後，反而全TLE了，我對scanf,printf不熟，請問有什麼錯誤的地方嗎?
有更動的地方已紅色字體標示
#include <stdio.h>
using namespace std;
int main(){
int dot,side,DOT1,DOT2,test;
while(scanf("%d%d",&dot,&side)){
int flag[dot]={0};
test=0;
for(int a=1;a<=side;a++){
scanf("%d%d",&DOT1,&DOT2);
flag[DOT1-1]++,flag[DOT2-1]++;
}
if( (flag[0]%2==0&&flag[dot-1]%2==1) || (flag[0]%2==1&&flag[dot-1]%2==0) ){
printf("%s\n","NO");
continue;
