请各位高手帮小弟看下,为啥总是WA~~ 晕啊~#include "stdio.h" #include "stdlib.h" typedef struct { int x; int y; } entry; int comp_x(const void* e1, const void *e2) { entry *p1 = (entry*)e1; entry *p2 = (entry*)e2; if ( p1->x != p2->x ) { return ( p1->x - p2->x ); } else { return ( p1->y - p2->y ); } } int comp_i(const void *p, const void *q) { return (*((int*)p) - *((int*)q) ); } int main() { int nCase; scanf("%d", &nCase); entry *entrys = (entry*)malloc( sizeof(entry) * nCase ); int i; for ( i = 0; i < nCase; i++ ) { scanf("%d%d", &entrys[i].x, &entrys[i].y); entrys[i].y = i; } qsort(entrys, nCase, sizeof(entry), comp_x); int *res = (int*)malloc(sizeof(int) * nCase); for ( i = 0; i < nCase; i++ ) { if ( i < entrys[i].y ) { res[i] = i; } else { res[i] = entrys[i].y; } } qsort(res, nCase, sizeof(int), comp_i); int *prints = (int*)malloc(sizeof(int) * nCase); for ( i = 0; i < nCase; i++ ) { *(prints+i) = 0; } int lev = 0; int r = 0; i = 0; for ( ;; ) { for ( r = 0; i < nCase && res[i] == lev ; i++ ) r++; //printf("%d\n", r); prints[lev] = r; if ( i == nCase ) break; lev = res[i]; } for ( i = 0; i < nCase; i++ ) { printf("%d\n", *(prints+i)); } free(entrys); free(res); free(prints); return 0; } Followed by: Post your reply here: |
