STRING METHODS COVERED: toUpperCase(), toLowerCase(), length(), charAt(), toString(), equals(), indexOf(), trim()

Problem 1: Pusheen is organizing a party for her friends! She is producing signed cards and giving them to all of her friends. She decides to take pictures of them to archive later. The OCR on Pusheen's smartphone transcribed most of the card properly, but due to the nature of signatures, the OCR might have mangled her name. Help Pusheen figure out how many errors the OCR made!

The OCR produced a string of length 7. This string should be compared character by character with pusheen, and the number of errors is the number of indices where the OCR'ed string does not match with pusheen.

Problem 2: Given a sentence, find the average length of each word.*
*define a word as a string of any kind of characters between spaces. Sentences have no punctuation
