I brainfarted and had a hard time trying to understand the instructions. > Incrementing is just like counting with numbers: xx, xy, xz, ya, yb, and so on. Increase the rightmost letter one step; if it was z, it wraps around to a, and repeat with the next letter to the left until one doesn't wrap around. I only managed to understand it by looking at solutions on the subreddit, figuring out the correct behavior: az -> ba, azzz -> baaa, azzzzz -> baaaaa etc. I also sped up the test case containing `ghi` as initial password, by looking for the leftmost invalid I, L or O and increase it, replacing all following chars with `a`. ghijklmn -> ghjaaaaa. |
