Welcome Party |Programming_info || python_problem_15

 New Year is shortly arriving and the students of St. Philip’s College of Business are eager to receive the freshers for the coming year. The Welcome party for the freshers is going to be organized in a week’s time and in connection to that the College Management has ordered the students to renovate their class room block. The Class room block has N rooms in it numbered from 1 to N. Each room is currently painted in one of the red, blue or green colors. Students are given configuration of colors of their class room block by an array consisting of N values. In this array, color red will be denoted by '1', green by '2' and blue by '3'.

 
The Management wanted the class room block to be repainted such that each class room has same color. For painting, Students have all the 3 color paints available and mixing any 2 color paints will result into 3rd color paint i.e

• 1 + 2 = 3
• 2 + 3 = 1
• 3 + 1 = 2

For example, if a room is already painted in green color, painting that room red color, will make the color of the room blue.

Also, students have many buckets of paint of each color. Simply put, you can assume that they will not run out of paint. Students are a bit lazy, so they does not want to work much and therefore, has asked you to find the minimum number of rooms they have to repaint (possibly zero) in order to have all the rooms with same color as told by the Management. Can you please help them?
 
Input Format:
First line of input contains an integer N, denoting the number of class rooms in the College’s class room block. Assume that the maximum value for N as 50.
Next line of input contains N values, denoting the current color configuration of rooms.

Output Format:
Print the minimum number of rooms that need to be painted in order to have all the rooms painted with same color i.e red, blue or green.

The Event Management Team had arranged for some exciting games after the mass worship and feast, where adults and kids of all ages participated very actively. "Chocolate Game" was organized for the kids which involved a standard chocolate of n by m pieces. More formally, chocolate is a rectangular plate consisting of n rows and m columns.

Two kids at a moment will play with the chocolate. First kid takes the chocolate and cuts it into two parts by making either a horizontal or vertical cut. Then, the second kid takes one of the available pieces and divides into two parts by either making a horizontal or vertical cut. Then the turn of first kid comes and he can pick any block of the available chocolates and do the same thing again. The player who cannot make a turn loses.
Write a program to find which of the kids will win if both of them play optimally. Output "Yes", if the kid who plays first will win, otherwise print "No".

Input Format:
The only line of the input contains two space separated integers n and m - the sizes of the chocolate.

Hanging Bridge |Programming_info || python_problem_11

 At the annual "KrackerJack Karnival", there was a newest attraction ever in the City, the "Hanging Bridge". Visitors will be able to walk 200ft on the bridge, hanging around 50ft above the ground, and enjoy a wide-angle view of the breathtaking greenery.

The Hanging Bridge was inaugurated successfully in co-ordination with the Event Manager Rahul. There is a limit on the maximum number of people on the bridge and Rahul has to now ensure the count of people on the bridge currently should not exceed the limit. He then approximately estimated that C adults and D kids who came to the show, were on the hanging bridge. He also noticed that there are L legs of the people touching the bridge.
Rahul knows that kids love to ride on the adults and they might ride on the adults, and their legs won't touch the ground and hence he would miss counting their legs. Also Rahul knew that the adults would be strong enough to ride at max two kids on their back.
Rahul is now wondering whether he counted the legs properly or not. Specifically, he is wondering is there some possibility of his counting being correct. Please help Rahul in finding it.
 
Input Format:
The only line of input contains three space separated integers C, D, L denoting number of the adults, number of the kids and number of legs of people counted by Rahul, respectively.

 Brendon is a little techno-whiz whose IQ is out of the charts. He has set up a laboratory at home for his research and development and was once approached by an Event Management firm to design them a Robot that would log all the activities carried out in an event at various instants during the day. This would help them keep a track and in smooth functioning of events.

Brendon, after long days of hard work designed one such Robot but wanted to test it on his own daily routines. His daily routine is very simple, he starts his day working in a computer, then he eats food and finally proceeds for sleeping thus ending his day. He has programmed his Robot to log the activities of him at various instants during the day.
Today it recorded activities that Brendon was doing at N different instants. These instances are recorded in chronological order (in increasing order of time). This log is provided to you in form of a string s of length N, consisting of characters 'C', 'E' and 'S'. If s[i] = 'C', then it means that at the i-th instant Brendon was working in Computer, 'E' denoting he was eating and 'S' means he was sleeping.
Write a program to tell whether the record log made by the robot could possibly be correct or not.

Input Format:
The only line of input contains the string s.
