# HackerRank CamelCase Solution

Hello Programmers, In this post, you will learn how to solve HackerRank CamelCase Solution. This problem is a part of the HackerRank Algorithms Series.

One more thing to add, don’t straight away look for the solutions, first try to solve the problems by yourself. If you find any difficulty after trying several times, then look for the solutions. We are going to solve the HackerRank Algorithms problems using C, CPP, JAVA, PYTHON, JavaScript & SCALA Programming Languages.

You can practice and submit all HackerRank problem solutions in one place. Find a solution for other domains and Sub-domain. I.e. Hacker Rank solution for HackerRank C ProgrammingHackerRank C++ ProgrammingHackerRank Java Programming, HackerRank Python ProgrammingHackerRank Linux ShellHackerRank SQL Programming, and HackerRank 10 days of Javascript.

As you already know that this site does not contain only the Hacker Rank solutions here, you can also find the solution for other problems. I.e. Web Technology, Data StructuresRDBMS ProgramsJava Programs Solutions,  Fiverr Skills Test answersGoogle Course AnswersLinkedin Assessment, and Coursera Quiz Answers.

## HackerRank CamelCase String

There is a sequence of words in CamelCase as a string of letters, s, having the following properties:

• It is a concatenation of one or more words consisting of English letters.
• All letters in the first word are lowercase.
• For each of the subsequent words, the first letter is uppercase and rest of the letters are lowercase.

Given s, determine the number of words in s.

Example

s = oneTwoThree

There are 3 words in the string: ‘one’, ‘Two’, ‘Three’.

Function Description

Complete the camelcase function in the editor below.

camelcase has the following parameter(s):

• string s: the string to analyze

Returns

• int: the number of words in s

Input Format

A single line containing string s.

Constraints

• 1 <= length of s <= 105

Sample Input

saveChangesInTheEditor

Sample Output

5

Explanation

String  contains five words:

1. save
2. Changes
3. In
4. The
5. Editor

## HackerRank CamelCase Solution

### CamelCase Solution in C

```#include <math.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <assert.h>
#include <limits.h>
#include <stdbool.h>

int main(){
char* s = (char *)malloc(10240 * sizeof(char));
scanf("%s",s);
int coun=0,i;
for(i=0;i<strlen(s);i++)
{
if(s[i]>=65 && s[i]<=90){coun++;}
}
printf("%d\n",coun+1);
return 0;
}```

### CamelCase Solution in Cpp

```#include <map>
#include <set>
#include <list>
#include <cmath>
#include <ctime>
#include <deque>
#include <queue>
#include <stack>
#include <string>
#include <bitset>
#include <cstdio>
#include <limits>
#include <vector>
#include <climits>
#include <cstring>
#include <cstdlib>
#include <fstream>
#include <numeric>
#include <sstream>
#include <iostream>
#include <algorithm>
#include <unordered_map>

using namespace std;

int main(){
string s;
cin >> s;
int t=1;
for (int i=0;i<s.length();i++)
if (isupper(s[i]))
t++;
cout<<t<<endl;
return 0;
}```

### CamelCase Solution in Java

```import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

public class Solution {

public static void main(String[] args) {
Scanner in = new Scanner(System.in);
String s = in.next();
int count = 1;
for(int i = 0; i<s.length(); i++){
char c = s.charAt(i);
if(c>='A' && c<='Z') count++;
}
System.out.println(count);
}
}```

### CamelCase Solution in Python

```#!/bin/python

import sys

s = raw_input().strip()
count=0
for i in s:
if i.upper()==i:
count+=1
print count+1```

### CamelCase Solution using JavaScript

```process.stdin.resume();
process.stdin.setEncoding('ascii');

var input_stdin = "";
var input_stdin_array = "";
var input_currentline = 0;

process.stdin.on('data', function (data) {
input_stdin += data;
});

process.stdin.on('end', function () {
input_stdin_array = input_stdin.split("\n");
main();
});

return input_stdin_array[input_currentline++];
}

/////////////// ignore above this line ////////////////////

function main() {
let array = s.split(/(?=[A-Z])/);
console.log(array.length);
}```

### CamelCase Solution in Scala

```import scala.io.StdIn._

object Solution extends App {
val counter = str.count(c => Character.isUpperCase(c))
println(counter + 1)
}```

### CamelCase Solution in Pascal

```var n,d,i:longint;
s:ansistring;
begin
n:=length(s);
d:=1;
for i:=1 to n do
if (ord(s[i])>64)and(ord(s[i])<91) then inc(d);
write(d);
end.```

## FAQ:

1. How do you solve the first question in HackerRank?

If you want to solve the first question of Hackerrank then you have to decide which programing language you want to practice i.e C programming, Cpp Programing, or Java programming then you have to start with the first program HELLO WORLD.

2. How do I find my HackerRank ID?

You will receive an email from HackerRank to confirm your access to the ID. Once you have confirmed your email, the entry will show up as verified on the settings page. You will also have an option to “Make primary”. Click on that option. Read more

3. Does HackerRank detect cheating?

yes, HackerRank uses a powerful tool to detect plagiarism in the candidates’ submitted code. The Test report of a candidate highlights any plagiarized portions in the submitted code and helps evaluators to verify the integrity of answers provided in the Test.

4. Does HackerRank use camera?

No for coding practice Hackerrank does not use camera but for companies’ interviews code submission time Hackerrank uses the camera.

5. Should I put HackerRank certificate on resume?

These certificates are useless, and you should not put them on your resume. The experience you gained from getting them is not useless. Use it to build a portfolio, and link to it on your resume.

6. Can I retake HackerRank test?

The company which sent you the HackerRank Test invite owns your Test submissions and results. It’s their discretion to permit a reattempt for a particular Test. If you wish to retake the test, we recommend that you contact the concerned recruiter who invited you to the Test and request a re-invite.

7. What is HackerRank?

HackerRank is a tech company that focuses on competitive programming challenges for both consumers and businesses. Developers compete by writing programs according to provided specifications. Wikipedi
