Hello Programmers In this post, you will know how to solve the Tanu and Head-bob Codechef Solution. The Problem Code: HEADBOB

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Codechef by yourself. If you find any difficulty after trying several times, then you can look for solutions.

### Problem

Tanu has got interested in signs and gestures that we use for communication. One such gesture is the head-bob.
When we want to signal “Yes” to someone, we move the head up-and-down. For “No”, the head is moved left-and-right, rotating about the vertical axis.
There is a peculiar way of gesturing “Yes”, commonly seen in India, by moving head sideways (rotating about the forward-back axis). This is called the Indian head-bob.

Tanu observed many people on the railways station, and made a list of gestures that they made. Usual “Yes” gesture is recorded as “Y“, no as “N” and Indian “Yes” gesture as “I“. (Assume no foreigner uses the Indian “Yes” gesture and vice-versa). Identify which of them were Indians, which were not Indian, and which one you cannot be sure about.

### Input

First line contains T, number of people observed by Tanu.
Each person is described in two lines. First line of the description contains a single integer N, the number of gestures recorded for this person. Next line contains a string of N characters, each character can be “Y”, “N” or “I”.

### Output

For each person, print “INDIAN” if he/she is from India, “NOT INDIAN” if not from India, and “NOT SURE” if the information is insufficient to make a decision.

### Constraints

• For 30 points: 1 ≤ T,N ≤ 100
• For 70 points: 1 ≤ T,N ≤ 1000

### Example

Input:

`35NNNYY6NNINNI4NNNN`

Output:

`NOT INDIANINDIANNOT SURE`

### Tanu and Head-bob CodeChef Solution in CPP

```#include<iostream>
using namespace std;
string solve_test()
{
int NO,YES, I, n=4;
NO = YES = I = 0;
cin >> n;
string signs;
cin >> signs;
for(int i =0; i < n; i++)
{
if(signs[i] == 'I')
return "INDIAN";
else if(signs[i] == 'Y')
return "NOT INDIAN";
}
return "NOT SURE";
}
int main()
{
int t;
cin >> t;
while(t--)
cout << solve_test()<<endl;
return 0;
}```
