PROGRAM
Candy Game
Mona set off with great zeal to the "Fun Fair
2017". There were numerous activities in the
fair, though Mona liked the Candy game.
Delicious candies were wrapped in colorful
foiled sheets with some random numbers on
each of the candies. The game coordinators
then formed many groups of few candies
together, such that each candy group makes
an integer and hid them all around the
room. The objective of the game is that the
players should look for the occurrences of
number four anywhere in the integers
(candy groups) placed in the room. Mona
started off with the game where there are
many such integers, for each of them she
should calculate the number of occurrences
of the digit 4 in the decimal representation.
Can you please help her in succeeding in
the game?
Input format
The only line of input contains a single
integer from the candy group.
Output format
Output should contain the number of
occurrences of the digit 4 in the respective
integer
from the candy groups that Mona gets.
Refer sample input and output for
formatting specifications.

Math Challenge
In connection to the National Mathematics
Day celebration, the Regional
Mathematical
Scholars Society had arranged for a Maths
Challenge Event where high school
students
participated in large numbers. The first
level of the challenge was an oral quiz,
followed by
a written test in the second round.
In the second round, the problem that the
students had to answer goes like this:
For every positive number ‘n’ we define a
function streak(n)=k as the smallest positive
integer k such that n+k is not divisible by
k+1.
E.g:
13 is divisible by 1
14 is divisible by 2
15 is divisible by 3
16 is divisible by 4
17 is NOT divisible by 5
So streak(13)=4.
Similarly:
120 is divisible by 1
121 is NOT divisible by 2
So streak(120)=1.
Now, define P(s, N) to be the number of
integers n, 1<n<N, for which streak(n)=s.
Write a
program to get the input as 's' and 'N' and
find the count of integers until N which has
the
streak value as 's'.
For example,
If s=3 and N=14.
If we compute streak value for the integers
from 1 to N, we can see only the integer 7
have
the streak value as 3, because
7 is divisible by 1
8 is divisible by 2
9 is divisible by 3
10 is NOT divisible by 4
Hence streak(7)=3.
So P(3, 14) = 1 and so the output is 1.
Input format
The first line of the input is an integer ‘s’
which is the streak value of an integer n.
The second line of the input is an integer
‘N’ which is the upper limit of numbers
until which
P(s, N) is calculated.
Output format
Output is an integer that gives the count of
integers until ‘N’ which has the streak value
as ‘s’.
Refer sample input and output for
formatting specifications.
