0400	MOV CX, [0500]	CX <- [0500]
0404	MOV AX, 0001	AX <- 0001
0407	MOV DX, 0000	DX <- 0000
040A	MUL CX	DX:AX <- AX * CX
040C	LOOP 040A	Go To [040A] till CX->00
0410	MOV [0600], AX	[0600]<-AX
0414	MOV [0601], DX	[0601]<-DX
0418	HLT	Stop Execution

MOV CX, [0500] loads 0500 Memory location content to CX Register
MOV AX, 0001 loads AX register with 0001
MOV DX, 0000 loads DX register with 0000
MUL CX multiply AX with CX and store result in DX:AX pair
LOOP 040A runs loop till CX not equal to Zero
MOV [0600], AX store AX register content to memory location 0600
MOV [0601], DX store DX register content to memory location 0601
HLT stops the execution of program

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order.
