PROBLEM:
The chef is trying to solve some pattern problems, Chef wants your help to code it. Chef has one number K to form a new pattern. Help the chef to code this pattern problem.
Program:
#include<bits/stdc++.h>
using namespace std;
int sum(int n) {
if (n <= 0)
return 0;
else
return (n * (n + 1) / 2);
}
int main()
{
//code
int t;
cin>>t;
while(t--){
int n;
cin>>n;
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= i + 1; j++) {
if (j != i + 1)
cout<<(j - 1) * n + i - sum(j - 1);
else
cout<<'*';
}
cout<<"\n";
}
}
