Question

do number 5

Using the MARS or SPIM simulator develop a program that will evaluate the following expression: 3*n + n * (n - 1) - 15 where n is stored in a data location and is set to 15. Your program should use the system calls to print the result and to exit the program. Section 2: Using the MARS or SPIM simulator develop a program that will implement the following conditional statement. If (n is even) {n = n/2; else n = 3 * n + 1 In this case, n is to be input by the user (assume they input a non-negative value), the conditional is performed, and the resulting n is to be output. Again, use the system calls for input, output, and exiting the program. Section 3: You are to take the conditional from the previous section and build a loop around it to find the Collatz sequence. The structure of tins would be: while(n > 1) {If(n is even) {n = n/2;} else {n = 3*n + 1:} Cout
