PROBLEM:
Subtract The Input.
Look at the INPUT and image carefully. Print the number of permutation of remaining set, modulo SUM OF 10^9 and 7 (i.e 10^9+7).
HINTS:
You are given an image which is a monogram (searching the image was to be done). In this image you can make all possible alphabets and numbers. You can check how each alphabet and number can be formed using monogram in this gif. The problem required you to print number of all possible permutations of the characters which were not in the given string ( hint from the title of the question, “Subtract the Input”) modulo (10^9 + 7).
