Subject : Assembly Language Programming Hw
Message : Write an assembler program that takes several words from standard input (keyboard, one word per input line) and outputs them sorted alphabetically, also one word per line. The number of input words is not limited. Hence, your program should store the input words in a linked list and sort them directly in the list. You are not allowed to use any auxilary arrays for temporary storage in your code. You can store the strings dynamically and organize pointers to strings in a linked list and swap the pointers by, say, the bubble-sort method instead of swapping the corresponding strings. You may use strcmp system call for comparing strings.
