Answer to Question #282041 in Assembler for Ahsan

Question

Q. Write an assembly language program to perform the following tasks:

Task 1 - Find the largest digit in your VUID.

Task 2 - Add the largest value to each index value and write it back at the respective index of the VUID. For example, if the numbers in VUID are 030400789, then after the task 2, the VUID should become 91291399161718.

Task 3 - Find the arithmetic series of the largest digit found in task 1 and store it in the “dx” register as shown in the sample screenshot.
