Submission Guideline (Read this before starting your assignment):

1. Your source code file must be named "main.c".
   (In case the assignment requires multiple files, the one containing the main function must be named "main.c")


2. Compress your completed source code file(s) into a zip file named "main.zip".
   (Do not include any folders inside your zip file.)


3. Send an email to csc1110@cse.cuhk.edu.hk with title "CSC1110 Assignment X Y" (without quotes).
   X is the assignment number.
   Y is your student ID (Enter all 8 digits).
   For example, your student ID is 08123456 and you want to submit your assignment 1, then the title will be:
   CSC1110 Assignment 1 08123456
   
   Attach the "main.zip" from the previous step to the email.
   
   Use your CUHK email account to submit the assignments. Other email accounts are not accepted.


4. Wait for an email reply. The reply should state whether your program has passed our tests.
   You will get the score for the assignment only if your program passes our tests.
   If no reply is received after a reasonable period of time. Try to submit again or contact the TA directly.

Specification:

Objective:	Reversing Array Get a list of integers from the user and store it into an array Get instructions from user and perform the corresponding operation Each instruction contains two numbers, you are to reverse the portion of the array indicated by these 2 numbers.
