#Array Practice

Listen to this song to get amped for Capeside high.

##Introduction

As administrator of the high school you have the ability to make changes to your records regarding staff and the students attending the high school. In an attempt to get organized and clean up some records you've decided to make the following changes:

Start by declaring the following methods in the FISAppDelegate.h:

• assigningTeacher:toRooms: that takes in two NSArray arguments, teacherRoster and rooms and returns a NSString.
• replacingTeacher:withTeacher: that takes two arguments, one NSArray argument named teacherRoster and one string argument named substitute and returns an NSArray.
• duplicateStudents:student: takes one NSArray argument mathClass and a NSString argument named student and returns an NSUInteger.
• signForPrinter: takes one NSArray argument named backwardsPhrase and returns a NSString.
• removeOpeningAndClosingShifts: takes one NSArray argument named schedule and returns and NSArray.

##Instructions 1. It's the first day of school at Capeside High! Get your teachers assigned their classrooms.

assigningTeacher:toRooms: should return a string with the teachers name and room assignment in this format "Welcome <#teacher's name>, your classroom is <#room>. each on a new line.

2. Oh no! Mrs. Jacobs has called out sick. We need an updated teacher roster.

replacingTeacher:withTeacher: should return a NSArray with the new list of teachers.

3. While clearing out your records you noticed that Principle Peskin has added duplicate student names to a math class.

duplicateStudents: should return a NSUInteger count of times a sudent's name appears.

4. Homecoming is finally here and your schools mascot, Pacey Witter needs his sign corrected.

signForPrinter: should return a string with the correct phrase. Somehow it was reversed and you need to set it right.

5. Your star student Joey has been taking too many shifts down at the Ice House Restaurant and it's effecting her shcool work. Help her fix the schedule by removing her opening and closing shifts from the scheudle. Being that this is a schedule, preserving the order of shiftworkers is important.

removeOpeningAndClosingShifts:schedule should return the updated schedule array that removes Joey's name from the first and last position.
