1. Create a function letterCounter() that takes a character array input and returns the number of uppercase characters and lowercase characters that are found in the character array as two seperate outputs: numCaps, numLower. DO NOT assume charArrayIn contains only letters. Hint: Check the reference sheet for functions that can help determine if a character is upper or lower case. The function header and an Texample run are provided below. function (numUpper, numLower] = letter Counter (charArrayIn) Determines the number of upper and lower case letters in the input char farray Inputs: charArrayIn - character array containing upper and lower case %letters *Outputs: numUpper- number of uppercase letters in charArrayIn numLower- number of lowercase letters in charArrayIn
