Write an asm 8086 language program that take 2 strings as input and computes the string distance between the 2 ,,, the string distance between 2 string os the sum of the difference the ASCII codes of character located at the same position in both strings .
As an example assume the first string to be encs432 and the second string to be encs533
Then the distance between 2 strings is computed as follows
Abs("e"-"e") +abs("n"-"n") +("c"-"c")+ ("s"-"s")+("4"-"5) ............= 4
