the sum of each pair's values is exactly equal to the target sales. Input The input to the function/method consists of three arguments: num, an integer representing the number of items; itemValues, a list of integers representing the item price; target, an integer representing the target sales. Output Return an integer representing the number of pairs having the sum of their prices equals to the target sales. Constraints 1 s num s 5* 105 Os temvaluesti] s 109 Osi< num Os target s 5* 109 Example Input: num = 9

Program #11. Show the ArrayStackADT interface 2. Create the ArrayStackDataStrucClass<T> with the following methods: default constructor, overloaded constructor, copy constructor, initializeStack, isEmptyStack, isFullStack, push, peek, void pop 3. Create the PrimeFactorizationDemoClass: instantiate an ArrayStackDataStrucClass<Integer> object with 50 elements. Use a try-catch block in the main( ) using pushes/pops. 4. Exception classes: StackException, StackUnderflowException, StackOverflowException 5. Show the 4 outputs for the following: 3,960 1,234 222,222 13,780
