Conditional Statements



It was Christmas Eve and the celebrations remembering the birth of Jesus were going on in full swing at the Catheral Chapel. 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.

Output Format:
Output a single line containing one word "Yes" (without quotes) if there is a sequence of moves leading to the winning of the person who moves first and "No" (without quotes) otherwise.

Hanging Bridge
 
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.

Output Format:
Output a single line containing a string "yes" or "no" (both without quotes) according to the situation.
Refer sample input and output for formatting specifications.

Sample Input 1:
1 1 4

Sample Output 1:
yes

Sample Input 2:
2 4 16

Sample Output 2:
no
Solution:  (c+d>=l/2 ->yes  else no

S7P1 - VALID INITIAL CONFIGURATION Valid Initial Configuration   Nurikabe logical game (sometimes called Islands in the Stream) is a binary determination puzzle. The puzzle is played on a typically rectangular grid of cells, some of which contain numbers. You must decide for each cell if it is white or black (by clicking on them) according to the following rules: All of the black cells must be connected. Each numbered cell must be part of a white island of connected white cells. Each island must have the same number of white cells as the number it contains (including the numbered cell). Two islands may not be connected. There cannot be any 2x2 blocks of black cells. Unnumbered cells start out grey and cycle through white and black when clicked. Initially numbered cells are white in color. Problem Statement: Write a program to check whether the given board configuration is a valid initial configuration. Below figure is the sample valid initial configuration.   I...
