// Mumbling
// Each char becomes n*chars where n is the index + 1, and the first char is capitalized divided by - instead of space.

// Only alphabets are passed as arguments for the accum(s) funciton

// Example: accum("ZpglnRxqenU") should return "Z-Pp-Ggg-Llll-Nnnnn-Rrrrrr-Xxxxxxx-Qqqqqqqq-Eeeeeeeee-Nnnnnnnnnn-Uuuuuuuuuuu
