// This time no story, no theory. The examples below show you how to write function accum;
//
// Examples:
//		accum("abcd") -> "A-Bb-Ccc-Dddd"
//		accum("RqaEzty") -> "R-Qq-Aaa-Eeee-Zzzzz-Tttttt-Yyyyyyy"
//		accum("cwAt") -> "C-Ww-Aaa-Tttt"
//
// The parameter of accum is a string which includes only letters from a..z and A..Z;
