Take a string as params return the first word that has the most repeated character if there are multiple words with the same number of repeated characters return the first word that appears in the string example: input: "Hello apple pie" output: Hello explanation: the word Hello and apple has the same number of repeated characters but Hello appears first in the string so the output is Hello if there are no repeated characters in the string return -1 as the output.
