hdu4221 greedy? (greedy)

I don't know why all the English questions ... Can't be good in Chinese ah ah ah

I saw the wrong test instructions.

#include <stdio.h> #include <algorithm>using namespace std;struct node {long long day,end;} C[100005];bool CMP (node X,node y) {if (x.end<y.end) return true;if (X.end==y.end&&x.day>y.day) return True ; return false;} int main () {int test,n,q=1;scanf ("%d", &test), while (test--) {scanf ("%d", &n), and for (int i=0;i<n;i++) scanf ("% LLD%lld ", &c[i].day,&c[i].end); sort (c,c+n,cmp); long long sum=0,max=0;for (int i=0;i<n;i++) {Sum+=c[i].day ; if (Sum-c[i].end>max) max=sum-c[i].end;} printf ("Case%d:%lld\n", Q++,max);} return 0;}

Oh, well, that's a mistake. Test instructions Even the sample can not understand
