Here is a link to a PDF that will help

Note: the code should look like something like that:

   INP
        STA 99
        INP
        ADD 99
        OUT
        HLT

Solution

solution:

INP // Read the 1st value
STA 91 // store
INP // Read the 2nd value
STA 92 // store
INP // Read in the 3rd value
STA 93 // store
LDA 92 // LOOP 1 and STEP 1:
SUB 91 //
BRP STEP2 // if both the r91 and r92 are in order, then don\'t swap them
LDA 92 // start with swapping registers
STA 99 // temp = r92
LDA 91
STA 92 // r92 = r91
LDA 99
STA 91 // r91 = temp
STEP2 LDA 93 // LOOP 1 and STEP 2
SUB 92
BRP STEP3 // If both the r92 and r93 are in order,then don\'t swap them
LDA 93 // start swapping registers
STA 99 // temp = r93
LDA 92
STA 93 // r93 = r92
LDA 99
STA 92 // r92 = temp
STEP3 LDA 92 // LOOP 2 and STEP 1
SUB 91
BRP STEP4 // if both r91 and r92 are in order, then don\'t swap them
LDA 92 // start swapping registers
STA 99 // temp = r92
LDA 91
STA 92 // r92 = r91
LDA 99
STO 91 // r91 = temp
STEP4 LDA 91 // please Write the sorted values
OUT
LDA 92
OUT
LDA 93
OUT
HLT // over/finsh
