Revolut Frontend Developer interview questions

One was to count the minimum times to paint a matrix (or similar). Another was to count the distance in a 3x3 number pad (like the number pad in a keyboard) given a sequence of numbers and a number pad, both in string form. And the last one was, given an array of anagrams, remove in the next item the previous anagram (don't remember the specifics of this one too, sorry).
