Write a MIPS program to demonstrate the operation of the following switch statement. switch (S) { case 5: A = A + 1; break; case 25: A = A - 1; break; default: A = A * 2; break; } Implement and simulate your solution. Allocate .data locations for the variables S and A, and load these values into registers before performing the switch statement on the registers. Run your program several times with different values for these variables, to...
