AnswersInput : 4 jars and 50 balls of different colors (Red, Green, Yellow, Blue) where each jar can contain a maximum of 100 balls.

Problem : When a user draws a red ball he looses his money while if he draws a ball of some other color his money is doubled. Arrange the balls in such a way that the user has highest probability to loose. Report Duplicate  Flag  PURGE

AnswersGiven a Binary tree and a pointer to some node in the tree, find the left and right neighbors of the input node. The neighbor nodes are on the same level/depth as of input node.

count is used to keep the count of node for internal logic while reversing the linked list.
