# Hackerrank Intro to Tutorials Challenges problem solution

In this Hackerrank Intro to Tutorial Challenges problem we have given a sorted array and a number, we need to print the index location of the integer in the array.

## Problem solution in Python programming.

```#!/bin/python3

import math
import os
import random
import re
import sys

#
# Complete the 'introTutorial' function below.
#
# The function is expected to return an INTEGER.
# The function accepts following parameters:
#  1. INTEGER V
#  2. INTEGER_ARRAY arr
#

def introTutorial(V, arr):
return arr.index(V)

if __name__ == '__main__':
fptr = open(os.environ['OUTPUT_PATH'], 'w')

V = int(input().strip())

n = int(input().strip())

arr = list(map(int, input().rstrip().split()))

result = introTutorial(V, arr)

fptr.write(str(result) + '\n')

fptr.close()```

## Problem solution in Java Programming.

```import java.io.*;
import java.util.*;

public class Solution {

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int value = sc.nextInt();
int cas = sc.nextInt();
ArrayList<Integer> ar = new ArrayList<Integer>();
for(int i = 0;i<cas; i++)
{
}

for(int n = 0; n < ar.size();n++)
{
if(ar.get(n) == value)
System.out.println(n);
}
}
}```

### Problem solution in C++ programming.

```#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;

int main() {

int V, n, temp;
cin >> V;
cin >> n;

int array[n];

for(int i = 0; i < n; i++) {
cin >> temp;
array[i] = temp;
}
for(int i = 0; i < n; i++) {
if(array[i] == V) {
cout << i << endl;;
}

}

return 0;
}```

### Problem solution in C programming.

```#include <stdio.h>
#include <string.h>
int main()
{
int V,N,a;
scanf("%d%d",&V,&N);
int i;
for(i = 0; i < N; i ++)
{
scanf("%d",&a);
if(a == V)
{
printf("%d\n",i);
return 0;
}
}
printf("-1\n");
return 0;
}```

### Problem solution in JavaScript programming.

```function processData(input) {
var inputArray = input.split('\n');
var V = parseInt(inputArray[0], 10);
var valueArray = inputArray[2].split(" ");
for(var i =0; i<valueArray.length; i++){
if(parseInt(valueArray[i],10) === V){
console.log(i);
break;
}
}
}

process.stdin.resume();
process.stdin.setEncoding("ascii");
_input = "";
process.stdin.on("data", function (input) {
_input += input;
});

process.stdin.on("end", function () {
processData(_input);
});```
