I am working on a function that is meant to add a series of numbers (starting from 1) at the end of each word within a string. Take a look at my current implementation:
function insertNum(str) {
var src = new Array();
src = str.split(" ");
return src[0] + "1 " + src[1] + "2 " + src[2] + "3 " + src[3];
}
insertNum("word word word word."); // should output "word1 word2 word3 word4."
insertNum("word word word."); // should output "word1 word2 word3."
Here is a solution...
function addNumbers(str) {
let count = 1;
return str.replace(/\w\b/g, function(match) {
return match + count++;
});
}
A simple method:
function addNumbersToString(input) {
let words = input.split(" ");
let newString = "";
for (let index = 0; index < words.length; index++) {
newString += words[index] + (index + 1) + " ";
}
return newString.trim();
}
int num = 1;
String text = "What a lovely day";
String words[] = text.split(" ");
for(String word : words){
System.out.print(word + num++ + " ");
}
