Answer 1

From iterating reversal through string in loop, if character is not a number then stop loop and save index value. Now just copy original string up to the founded index value.. There may be other ways you can try..

Answer 2

You're using extended ASCII character '×' as multiplication operator represeentation. During an attempt I found that it may add to the challenge more difficulty of finding last position of that character in a string (in C# code)
