题目描述
A sequence contains n integers, can you make a judgment of whether the sequence is strictly increasing.
输入描述:
There are multiple test cases. The first line is an positive integer indicating the number of test cases.
For each test case:
Line 1. A positive integer n, standing for the number of elements in the sequence.
Line 2. This line contains n integers, a1, a2, ..., an(2<=n<=100, 0<=ai<=1000) separated by space.
For each test case:
Line 1. A positive integer n, standing for the number of elements in the sequence.
Line 2. This line contains n integers, a1, a2, ..., an(2<=n<=100, 0<=ai<=1000) separated by space.
输出描述:
For each test case, output one line. If the sequence is strictly increasing, print "Yes", else print "No".
数组中，若出现“后一个数大于等于前一个数”，则该数组非递增
#include<iostream>

while(t--)
{

for(int i=0;i<n;i++)
{
cin>>sum;
a.push_back(sum);
}
for(int i=0;i<n-1;i++)
{
if(a[i]>=a[i+1])
{
flag=false;
cout<<"No"<<endl;
break;
}
}
if(flag) cout<<"Yes"<<endl;
}
return 0;
