main(List<String> args) {
var sum = 0;
var given_list = [1, 2, 3, 4, 5];
for (var i = 0; i < given_list.length; i++) {
sum += given_list[i];
}
print("Sum (for loop): ${sum}");
sum = 0;
given_list.forEach((e) => sum += e);
print("Sum (forEach): ${sum}");
sum = given_list.reduce((value, element) => value + element);
print("Sum (reduce): ${sum}");
sum = given_list.fold(0, (previous, current) => previous + current);
