车辆调度—模拟栈的操作

#include<iostream>
#include<cstdio>
using namespace std;
const int MA=1005;
int stack[MA];
int a[MA];
int top=-1;
int main(){
	int n;
	cin>>n;
	for(int i=1;i<=n;i++) scanf("%d",&a[i]);
	int cur=1;//cur为进过栈的数字最大值+1,初始cur为1
	for(int i=1;i<=n;i++){
		while(stack[top]<a[i]){  //进栈 cur 到 a[i] 
			stack[++top]=cur++; 
		}
		if(stack[top]==a[i]) top--;//出栈a[i]
		else{
			printf("NO
");
			return 0;
		}
	}
	printf("YES
");
	return 0;
}
