Write a method that returns a string for the "funny" binary representation of the positive integer 'num'. What makes it a "funny" binary representation is that instead of using 1's and 0's, you are using whatever character(s) are represented by the strings 'one' and 'zero'. For example, the integer 4 can be represented in binary as "100", but if 'one' was "!" and 'zero' was "[", you would instead represent it as "![[". Note: 'one' COULD be "1" and 'zero' COULD be "0", in which case your resulting string should look exactly like 'num' represented in binary would look. Preconditions: 'num'>0; 'one' and 'zero' are non-emptry strings.
