某个 【】 在昨天考试时候使用了快读快些并用这代码写了 T1。WA 70 分
#include <iostream>
#include <cmath>
#include <algorithm>
#include <cmath>
#include <cstring>
#include <queue>
#include <vector>
using namespace std;
#define int long long
namespace Syxqwq {
inline int read() {
register int x = 0, s = 1;
char c = getchar();
while(c > '9' || c < '0') {
if(c == '-') s = -1;
c = getchar();
}
while(c >= '0' && c <= '9') {
x = (x << 1) + (x << 3) + (c - '0');
c = getchar();
}
return x * s;
}
void Write(int x) {
if(x == '-') {
putchar('-');
x = -x;
}
if(x > 9) Write(x / 10);
putchar(x % 10 + '0');
}
inline void write(int x, char c) {
Write(x);
putchar(c);
}
}
using namespace Syxqwq;
priority_queue<int> que;
signed main() {
int n, m;
cin >>n >> m;
for(int i = 1; i < m; ++i) {
int x;cin >> x;
que.push(x);
}
for(int i = m; i <= n; ++i){
int x;cin >> x;
que.push(x);
int y = que.top();
write(y, ' ');
que.pop();
}
return 0;
}
但是把它 Write() 函数改成
#include <iostream>
#include <cmath>
#include <algorithm>
#include <cmath>
#include <cstring>
#include <queue>
#include <vector>
using namespace std;
#define int long long
namespace Syxqwq {
inline int read() {
register int x = 0, s = 1;
char c = getchar();
while(c > '9' || c < '0') {
if(c == '-') s = -1;
c = getchar();
}
while(c >= '0' && c <= '9') {
x = (x << 1) + (x << 3) + (c - '0');
c = getchar();
}
return x * s;
}
void Write(int x) {
if(x < 0) {
putchar('-');
x = -x;
}
if(x > 9) Write(x / 10);
putchar(x % 10 + '0');
}
inline void write(int x, char c) {
Write(x);
putchar(c);
}
}
using namespace Syxqwq;
priority_queue<int> que;
signed main() {
int n, m;
cin >>n >> m;
for(int i = 1; i < m; ++i) {
int x;cin >> x;
que.push(x);
}
for(int i = m; i <= n; ++i){
int x;cin >> x;
que.push(x);
int y = que.top();
write(y, ' ');
que.pop();
}
return 0;
}
原因是某【】把 x < 0 写成了 x == '-'，于是 T1 就飞走了
