After visiting a node, if we determined that it can possibly lead to a solution we will expend it. The node is called promising nonpromising root leaf

The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.

In the game Rock paper Scissors, two players simultaneously choose one of three options: rock, paper, or scissors. If both players choose the same option, then the result is a tie. However, if they choose differently, the winner is determined as follows: Rock beats scissors, because a rock can break a pair of scissors. Scissors beats paper, because scissors can cut paper. Paper beats rock, because a piece of paper can cover a rock. Create a game in which the computer randomly chooses rock, paper, or scissors. Let the user enter a character, r, p, or s, each representing one of the three choices. Then, determine the winner. Save the application as RockPaperScissors.cs.
