Problem 1 - Write a RISC-V assembly program to read 3 unsigned integers and display the smallest integer (for read and display use ecall). Problem 2- Write a RISC-V assembly program to read two numbers (x and y). If both x and y are positive, display 2, if only one of them is positive display 1, otherwise display 0 (for read and display use ecall). Problem 3 - Write a RISC-V assembly program that include a main calling program and a procedure called rec_lin. The main program reads input n and call the recursive procedure rec_lin (define below). The argument n will be passed to rec_lin in register x10, and the procedure should also return the result in register x10. The main program should then display the result (for read and display use ecall). If n5 rec_lin(n) = 5 Else rec_lin(n) = 4rec_lin(n-5)+n
