Crossed Words

Crossed Words

The mission is in Blocked Mode. Access to the solutions is blocked for a day or two (even after you share your own), until we'll have enough solutions for you to check. All users who've solved the mission will get the notifications about their opening.

In a crossword game, the player fills a rectangle with black and white squares, where each blank row and column must be filled with a word. The horizontal words intersect with the vertical words in common letters. In this mission only two words are given.

Given a horizontal word and a vertical word, your task is to find the best crossing letter between them, defined as the letter that allows the rightmost crossing in the horizontal word and, in the event of a tie, the lowest crossing in the vertical word.

You need to return a tuple of two integers: 1-based indexes of common letter in horizontal and vertical words respectively. If there is no common letter return -1, -1.


Input: Two uppercase strings (str).

Output: Tuple of two integers (int).


assert crossed_words("PATO", "PELE") == (1, 1)
assert crossed_words("ANJO", "MENTORA") == (4, 5)
assert crossed_words("URUBU", "POLIVALENTE") == (-1, -1)

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

checkio serv -d

Alternatevly, you can install Chrome extension or FF addon

checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
