Given a sentence, the task is to rewrite in Google Case. It is a style of writing where we replace all lower case letters into upper case letters leaving the initial of all the words.
Examples :
Input : gEEks fOr GeeKs Output : gEEKS fOR gEEKS Input : I got intern at neveropen Output : i gOT iNTERN aT gEEKSFORGEEKS
A simple solution is to convert the whole string into an upper letter and then traverse the given string while traversing we replace the initial of all words with small.
Implementation:
C++
// C++ program to convert a // sentence to gOOGLE cASE.#include <bits/stdc++.h>using namespace std;string convert(string str){ // Empty strings string w = "", z = ""; // Convert input string to upper case transform(str.begin(), str.end(), str.begin(), ::toupper); str += " "; for(int i = 0; i < str.length(); i++) { // Check if character is not a space // and adding it to string w char ch = str[i]; if (ch != ' ') { w = w + ch; } else { // Converting first character // to lower case and subsequent // initial letter of another // word to lower case z = z + char(tolower(w[0])) + w.substr(1) + " "; w = ""; } } return z;}// Driver codeint main(){ string str = "I got intern at neveropen"; cout << convert(str) << endl; return 0;}// This code is contributed by rutvik_56 |

Time Complexity: O(n)
Auxiliary Space: O(n)
The above solution requires two traversals of string. An efficient solution is to do in a single traversal. The idea is to keep track of spaces. After every space, print character to lower, else print in upper.
