Simple challenges

S1

Write a program that enters 3 numbers such as 5, 8, 3 and then outputs them in reverse as in 3, 8, 5.

>        INP
        STA 0
        INP
        STA 1
        INP
        OUT
        LDA 1
        OUT
        LDA 0
        OUT

S2

Write a program that asks for two numbers. It then outputs the first number subtracting the second number and then outputs the second number subtracting the first number. Eg if 3 and 5 were entered the first sum would be 3-5 and the second sum would be 5-3.

>        INP
        STA 0
        INP
        STA 1
        SUB 0
        STA 2
        LDA 0
        SUB 1
        OUT
        LDA 2
        OUT

S3

Write a program that outputs the negative of a positive number. So if 7 is entered -7 is output.

>        INP
        STA 0
        SUB 0
        SUB 0
        OUT

Intermediate challenges

I1

Ask the user for 2 numbers. If they are the same then double the number and print it out. If they are different then print them both out individually.

>        INP
        STA 0
        INP
        STA 1
        SUB 0
        BRZ double
        LDA 0
        OUT
        LDA 1
        OUT
        HLT
double  ADD 0
        ADD 0
        OUT

I2

Ask the user for 2 numbers. Print out biggest, then the smallest.

>        INP
        STA 0
        INP
        SUB 0
        BRP bigger
        ADD 0
        STA 1
        LDA 0
        OUT
        LDA 1
        OUT
        HLT
bigger  ADD 0
        OUT
        LDA 0
        OUT

I3

Ask the user for 2 numbers, print out the result of the biggest number minus the smallest number.
