There are N intermediate stations between two places A and B. Find the number of ways in which a train can be made to stop at S number of these intermediate stations so that no two stopping stations are consecutive. Write a python module Station.py for above and import the module in RollNo_W12B_3.py. In RollNo_W12B_3.py, define a function Get_Stations(N, S)  which takes value of N & S and return integer result as shown in example by calling the appropriate function implemented in Station.py module. Also handle the possible exceptions and display the exception message in form of string.

Earthquake python program. shreya is learing about earthquakes and stumbles accroess an interesting fact: the magnitude of on earthquake is a logarithmic scale of the energy realeased by the earthquake. it is known that each time the magnitude increases by 1, the amount of energy ets multiplied by 32. your tas is to help shreya by determining, how many times is the amount of energy of a magnitude a earthquake compared to that of a magnitude B earthquake?

I/p : a=6 & b=4, 6 is 2 greater than 4, so a magnitude 6 earthquake has 32*32=1024 times as much energy as a magnitude 4 earthquake has. so, the output is 1024

Input : 6 4

 Kalinjar Fort is a popular tourist place in Bundelkhand, Utter Pradesh. Everyday peoples registered to visit Fort as token provided based on first come basis. Everyday limited numbers of peoples are allowed to visit. The management selects a number N1 randomly every day and generates another number N2 as count of the total number of set bits (i.e., total no. of 1^s) in binary representation of all numbers from 1 to N1. For example, N1=3 then N2=4 [1(01) +2(10) +3(11)]. So, write a python module CountBit.py to find N2 using N1. You need to import this module in RollNo_W12B_2.py. In RollNo_W12B_2.py, define a function Get_Token(n) which takes a number and return value as shown in example by calling the appropriate function implemented in CountBit.py module.

Given a string of numbers S, the task is to find the maximum value from the string S, you can add a ‘+’ or ‘*’ sign between any two numbers.

For example, S=891. As 8*9*1 = 72 and 8*9+1 = 73. So, 73 is maximum.

Write a python module MaxValue.py for solve the above task. You need to import this module in RollNo_W12B_1.py. In RollNo_W12B_1.py, define a function Find_Max(n) which takes a string and return maximum value or error message as shown in example by calling the appropriate function implemented in MaxValue.py module. Also handle the possible exceptions and display the exception message in form of string.

Friend and Enemy

A group of F friends went to a haunted house.Each member was given a shirt with a number on it ranging from 1 to F. As they entered the haunted house, one of them was kidnapped and an enemy joined them.But unfortunately, the enemy didn't wear the shirt with the same number as the kidnapped one, instead wore the same as some other person.Find the numbers on the shirts of the enemy and the kidnapped person.

Input

The input is a single line containing space-separated positive integers from 1 to F.

Output

The output should be a single line containing the shirt numbers of the enemy and kidnapped person separated by a space.

Explanation

The given array is 3 1 5 2 1.

In the range from 1 to 5, the number 1 has occured twice and 4 is the missing number. So, 1 belongs to the enemy's shirt, and 4 belongs to kidnapped.Hence, the output should be 1 4.

Andrew 300

Mary 1000

Jane 400

Tobey 1000

output:-

Mary 2

explanation output:- both tobey and mary have the biggest investment . as mary is smallest in lexicographic name than tobey and found at index 2 the output is "mary 2"

a square matrix A of dimensions NxN. You need to apply the below given 3 operations on matrix A.

Rotation: It represented as R S where S is integer in {90, 180, 270, 360, 450, .} which denotes the number of degrees to rotate. You need to rotate matrix A by angle S in the clockwise angle of rotation(S) will always be in multiples of 90 degrees.

Update: It is represented as U X Y Z. In initial matrix A (as given in input), you need to update the element at row index X and column index Y with value Z.

After the update, all the previous rotation operations have to be applied to the updated initial matrix.

Query: It is represented as Q K L. need to print the value at row index K and column index L of the matrix A.

Next N lines contain N space-separated integers Aij (i - index row, j - index of column)
