1-Write an application using a hash table that finds all the pairs of two integers within the below array that add up to 12.
Array = {4,9,6,13,5,3,2,8}
2-Develop an application that stores characters A, B and C in a queue array and then displays both the size and the first-in element of the stack. The application should then remove the first element of the queue and then display both the size and the first-in element of the queue again. Appropriate queue methods should be used to add, delete and display characters.
3-Develop an application that store characters A, B and C in a stack array and then displays both the size and the last-in element of the stack. The application should then remove the last element of the stack and then display again both the size and the last-in element of the stack. Appropriate stack methods should be used to add, delete and display characters.
4-Write a program that merges two ordered-list objects of integers into a single ordered list object of integers. Use the merge method of class ListMerge to receive references to each of the list objects to be merged and return a reference to the merged list object.
5-Binary search is an important
