Multiply ints without arithmetic/bitwise operators

[wzhouwzhou]

#1 solves this problem:

I have two variables a and b containing ints i want to multiply
the task is to make a one-line function in js that multiplies these numbers without any arithmetic/bitwise operators
ie use of + - = | & >> * / etc

Do other people have solutions, perhaps in other languages, that accomplish this?

@devarakondapranav @wzhouwzhou doesn't len() use the '+' operator?

[wzhouwzhou]

@akshayrpatel Technically yes, but it's a built-in so I don't really count + in builtins
The solution in #1 relies on <String>#repeat which at its core also uses + in it's description here

A Vim script solution with the same approach: #215.

Nice, I'll look into it!
