C. Nastya and Strange Generator (思维&找规律)
思路:
AC代码:
#include<bits/stdc++.h>
using namespace std;
int main(){
int t;
scanf("%d",&t);
while(t--){
int n;
scanf("%d",&n);
vector<int>a(n+1);
for(int i=1;i<=n;i++) scanf("%d",&a[i]);
int ok=1;
for(int i=2;i<=n;i++)
if(a[i]>a[i-1]&&a[i]-a[i-1]!=1){
ok=0;
break;
}
puts(ok?"Yes":"No");
}
return 0;
}
