Program to replace a word with asterisks in a sentence
For the given sentence as input, censor a specific word with asterisks ‘ * ‘.
Example :
Input : word = “computer”
text = “GeeksforGeeks is a computer science portal for geeks. People who love computer and computer codes can contribute their valuables/ideas on computer codes/structures on here.”
Output : GeeksforGeeks is a ******** science portal for geeks. People who love ******** and ******** codes can contribute their valuables/ideas on ******** codes/structures on here.
The idea is to first split given sentence into different words. Then traverse the word list. For every word in the word list, check if it matches with given word. If yes, then replace the word with stars in the list. Finally merge the words of list and print.
