Hello folks!\n\nI have an array of string that represents a DNA sequence and I would like to check if it has a character sequence of 4 letters O, N or Z in any direction. As example, I have this array:\n\nvalues = ["ZBNONO", "ZBONNZ", "BOBBNB", "ONONNN", "ZZZZBO", "BZOZBN"]\n\nhttps://i.stack.imgur.com/2fuV8.png\n\nI\'m totally stuck to solve this problem and I would like to know what is the best algorithm to solve it.\n\nTo be a valid array, it must have more than 1 sequence of letters.\n\nAny help, please?
