Write a program to input two characters from the keyboard. Find the difference (d) between their ASCII codes. Display the following messages:
If d = 0 : both the characters are same.
If d \< 0 : first character is smaller.
If d > 0 : second character is smaller.
Sample Input :
D
P
Sample Output :
d = (68 - 80) = -12
