The following MARIE assembly program first creates an array of 5 numbers. The array starts at memory word #30 and ends at memory word #34. It contains integers 3, 10, 17, 24, 31.

After creating the list in the memory, the program asks for an address (suppose we will enter 0x33, that is HEX 33). The program is supposed to swap the contents of this memory address with the contents of the next memory address (HEX 34).

The beginning part of a working program is given below and you will complete the rest. Submit your code and sample run screenshots, include comments in your program.

NOTE/HINT: If we had an instruction for register indirect load instruction (something like LOAD_RI) that would have solved the problem: The ID of the AC register is 4. Therefore LOAD_RI 4 would have used the contents of register-4 (AC) as the memory address of the data. But we do not have an instruction like LOAD_RI, therefore we will make use of memory-indirect addressing for this problem.
