/* Lottery Winners - A lottery ticket buyer purchases 10 tickets a week,
always playing the same 10 5-digit "lucky" combinations. This program
initializes an array with these numbers and then lets the player enter
this week's winning 5-digit number. The program performs a linear search
through the list of the player's numbers and report whether or not one of
the tickets is a winner this week. The numbers are:
13579 26791 26792 33445 55555
