Write a method named countcoins that accepts as its parameter a scanner for an input file whose data represents a person's money grouped into stacks of coins. your method should add up the cash values of all the coins and print the total money at the end. the input consists of a series of pairs of tokens, where each pair begins with an integer and is followed by the type of coin, which will be either "pennies" (1 cent each), "nickels" (5 cents each), "dimes" (10 cents each), or "quarters" (25 cents each), case-insensitively. a given coin might appear more than once on the same line.
