When I was a student of 1st year B. Sc Engineering and I am appearing my final examination of subject Physics, I found some problem. When I was reading the topic “Mean Free Path” as illustrated in figure, I noticed something related to it. From the definition I came to know, “The distance traversed by a molecule between two collisions is known as Mean Free Path”.
But my problem was in finding the number of collision at a definite distance & mean free path. I solved my problem after a hard work, but at this moment one of my friend asking me to solve the problem again. I tired to solve it again, please help my friend to find the answer.
Input
The input will be two numbers indicating – 1) Mean Free Path 2) Path Length respectively. Your task is to find out the numbers of collision. Hey, relax you have to do some extra work in some case. Where you will find a character enclosed with the given with the number. The character means 10 (ch) , where ch=a…….z. The value for a=0…. z=25
Output
The output will be a positive integer number. If the answer comes in fractional value we should apply the floor or ceil method.
Sample Input
10 100a
20 10b
30 3c
Sample Output
The number of collision is = 10.
The number of collision is = 5.
The number of collision is = 10.

Problem:
When I was rechecking my online account I noticed that t made very simple to hard solution in my little programming career (I think so). At that time I got bad fever and fully in bed rest for one week. After recovering from it I wanted to start my journey again. But I can't concentrate so I take a mathematic book for reading. When I was reading the topics prime number and algorithm of prime generation I noticed I peculiar relation. Some prime number can be another prime number after some modification. I give it auto prime which is as follows: “after adding one with a prime number divide it by two and check the answer”. The result may be a prime number. e.g. 3 is a prime number, adding one and divided by two it becomes two which is a prime number. Take one as a prime.
Input & Output:
The input will be two numbers. You have to find the number of auto prime between them. Input will be terminated by 0.
Sample Input:
1 5
0
Sample Output:
3

Flower is a beauty of nature, we know everybody. Three students named Mizan, Ripon & tareq are the beauty of a varsity like flower. They also like flowers, but the choice is not same. Mizan likes odd number of rose, Ripon likes even number of belly, and Tareq likes kamini. One day one of their friends named babu brought a lot of flowers to give them for their outstanding work. At first babu put all of the flowers to a table. Then he gave 9th rose to Mizan, 14th belly to Ripon, 34th kamini to tareq. That time a nice thing happened, Ripon & Mizan were so angry when they took the flowers instead of pleasure but tareq is ok. Babu was strange and asked a question to tareq “what's matter, do you know”? He told babu, “Mizan does not like the family of 3 & Ripon does not like the family of 5 & 7 but not 7”.Family of 3? Babu asked. Tareq said multiple of 3.Babu did not realize the whole matter. Suppose you are expert in C, now you help him to realize by coding in C.
(Note: mind it except tareq Mizan & ripon likes to give the last flower to babu for their happiness)
Input:
For Mizan u take input m, for tareq t, for ripon r. Than you take input for how many flowers babu brought to give them(0<=h<155).m ,r ,t may be capital or small.
Output:
Now you tell for r (ripon) which flowers he wants to take and so on? You also tell how many flowers he takes? Please show your output in following format.
Sample input:
M
12
r
12
t
12
y
Sample output:
2 4 6 7 8
5
1 5 7 11
4
1 2 3 4 5 6 7 8 9 10 11 12
12
Please take the right input.
