/*

Using the JavaScript language, have the function NumberSearch(str) take the
str parameter, search for all the numbers in the string, add them together,
then return that final number. For example: if str is "88Hello 3World!" the
output should be 91. You will have to differentiate between single digit
numbers and multiple digit numbers like in the example above. So "55Hello"
and "5Hello 5" should return two different answers. Each string will contain
at least one letter or symbol.

	var totalSum = 0;

	var currentNum = 0;

	for (var i = 0; i < str.length; i++) {

		if (str[i].match(/[0-9]/)){

			currentNum = parseInt(str[i]);
			//console.log("currentNum: " + currentNum);


			if (str[i+1] && str[i+1].match(/[0-9]/)) {
				remainingStr = str.substring(i+1);
				//console.log("remainingStr: " + remainingStr);

					if (remainingStr[0].match(/[0-9]/)) {
						//console.log('matched');
						nextNum = parseInt(remainingStr[0]);
						currentNum = currentNum * 10 + nextNum;
