3. Examine the pseudocode below, then find and correct all the bugs.
// A high school is holding a recycling competition, and this program
// allows a user to enter a student's year in school (1 through 4) and
// number of cans collected for recycling. Data is entered continuously
// until the user enters a 9 for the year. After headings, output is four
// lines -- one for each school year class. Find and fix all bugs.
