JAVA QUESTION

I have an array

String array [] = {"101", "010", 111"}

I have an input of "000" that I want to compare to each value in the array and count how many times they Differ.

So String input = "000"
CODE A FUNCTION THAT ACCEPTS THE ARRAY AND THE INPUT VARIABLE AS PARAMETERS.

IN THIS FUNCTION, CODE A FOR LOOP THAT COMPARES THE String input to each element of the array ,COUNTS how many time they differ for each element and return the difference

For example, input "000", differs 2 times with element "101" of the array.

Answer 1

• As you mentioned in the comment section, i'm returning count value for each using loop in main.
• if you want me to change/add anything, please let me know by commenting.
