#ATTENDANCE QUESTION #1

#Let a:=FIRST DIGIT of your RUID
#Let b:=SECOND DIGIT of your RUID
#Let c:=FIFTH DIGIT of your RUID
#Let d:=SIXTH DIGIT of your RUID
#HOW MANY WALKS IN MANHATTAN ARE THERE (NOT USING BDWAY)
#From CORNER of min(a,b) St. and min (c,d) Ave
#to      "      max(a,b) St. and max (c,d) Ave
#Walking in the positive direction


#A1. MY ANSWER TO THE FIRST ATTENDANCE QUESTION IS:
#a = 1, b = 8, c = 0, d = 0
# The points are on the same line, so there is only one way.

#Q2. THE  SECOND ATTENDANCE QUESTION WAS:

#CONSIDER YOU RUID AS A WORD of LENGTH 9 in
#THE 10-letter "ALPHABET" {0, 1, 2, ..., 9}
#HOW MANY WAYS TO REARRANGE YOUR RUID

#A2. MY ANSWER TO THE  SECOND ATTENDANCE QUESTION IS:

# My RUID is as follows: 177002257
# There are three repeating 7s, two repeating 0s, and 2 repeating 2s.  There would be a total of 9!/(2!2!3!)=15120 ways.
