using pseudocode debug the following 3 programs

Question

// A high school is holding a recycling competition
// This program allows a user to enter a student's
// year in school (1 through 4)
// and number of cans collected
// Data is entered continuously until the user wants to quit
// After headings, output is four lines
// one for each school year class
