I tired two approaches. First was brute foce (first check for the powerful integer, check if it's greater than the limit, then check if it's a suffix. This works but it doesn't scale. Then the next method I came up with was using a Queue and BFS for "prepend" and ge the candidate numbers and check. That didn't pass all testcases so I just ran to the editorial to see what they have and it was pretty interesting. Combination was my go to.
