(a) Implement the C code snippet in RISC-V assembly language. Use so and s1 to hold the variable i, and min idx in the function selectionSort. Be sure to handle the stack pointer appropriately. Clearly comment on your code. (b) Assume that the selectionSort is the function called. Draw the status of the stack before calling selectionSort and during each function call. Indicate stack addresses and names of registers and variables stored on the stack; mark the location of sp; and clearly mark each stack frame. Assume the sp starts at 0x8000.
