Answer 1

match*$ means - match, from beginning to end, any character that appears zero or more times. Basically, that means - match everything from start to end of the string. ... The pattern says - the string should start with Matt and end with Jones and there can be zero or more characters (any characters) in between them.

Answer 2

Answer:
