Camel case of a given sentence

Given a sentence, task is to remove spaces from the sentence and rewrite in Camel case. It is a style of writing where we don’t have spaces and all words begin with capital letters.


Input  : I got intern at techcodebit
Output : IGotInternAtTECHCODEBIT

Input :  Here comes the garden
Output : HereComesTheGarden

Simple solution: First method is to traverse sentence and one by one remove spaces by moving subsequent characters one position back and changing case of first character to capital. It takes O(n*n) time.

Efficient solution : We traverse given string, while traversing we copy non space character to result and whenever we encounter space, we ignore it and change next letter to capital.

Below is c++ code implementation

// CPP program to convert given sentence
/// to camel case.
#include <bits/stdc++.h>
using namespace std;
// Function to remove spaces and convert
// into camel case
string convert(string s)
    int n = s.length();
    int res_ind = 0;
    for (int i = 0; i < n; i++) {
        // check for spaces in the sentence
        if (s[i] == ' ') {
            // conversion into upper case
            s[i + 1] = toupper(s[i + 1]);
        // If not space, copy character
            s[res_ind++] = s[i];       
    s[res_ind] = '\0';
    // return string to main
    return s;
// Driver program
int main()
    string str = "I get intern at <a href="#">techcodebit</a>";
    cout << convert(str);
    return 0;
