PROBLEM:

A Unique Sequence is defined as a sequence that do not have any repeating elements in it.
You will be given any random sequence of integers, and you have to tell whether it is a Unique Sequence or not.

EXPLANATION:

Read an array of size n, Traverse through the array and Compare each element with the other using nested for loops .if two elements are same print “ugly” else print “beautiful”.

SOLUTIONS:

Setter's Solution

#include <bits/stdc++.h>
#include <math.h>
using namespace std;

#define ll long long
#define ff first
#define ss second
#define pb push_back
#define vi vector
#define vll vector

int main()
{
#ifndef ONLINE_JUDGE
freopen(“in.txt”, “r”, stdin);
freopen(“out.txt”, “w”, stdout);
#endif

``````std::ios::sync_with_stdio(false);

int t;
cin >> t;
while (t--)
{
int n;
cin>>n;
int arr[n];
bool ans = true;
for(int i=0;i<n;i++){
cin>>arr[i];
}
for(int i=0;i<n;i++){
for(int j=i+1;j<n;j++){
if(arr[i] == arr[j]){
ans = false;
}
}
}
if(ans == true){
cout<<"beautiful"<<endl;
}else{
cout<<"ugly"<<endl;
}

}
