- Finding the common members of two dynamic arrays: Write a program that first reads two arrays and then finds their common members (intersection). The program should first read an integer for the size of the array and then should create the two arrays dynamically (using new) and should read the numbers into array1 and array2 and then should find the common members and show it. Note: The list of the common members should be unique. That is no member should be listed more than once. Tip: A simple for loop is needed on one of the arrays (like array1) and one inner for loop for on array2. Then for each member of array1, if we find any matching member in array2, we record it. Sample run: Enter the number of elements of array 1: 7 Enter the elements of array 1: 10 12 13 10 14 15 12 Enter the number of elements of array 2: 5 Enter the elements of array 2: 17 12 10 19 12 The common members of array1 and array2 are: 12 10It’s possible to make a class that acts like an array.

- Translator Using as a basis the program that allows to deal cards from a deck to a player's hand, add functionality that allows to update the deck of cards. Updating the deck of cards involves moving the cards from the deck to the beginning of the vector as the player requests a new card. At each deal, the cards in the deck must be printed to make the code in c language. The following functions must be implemented additionally: updateDeck. - This function receives two arguments: a vector with the deck of cards to update and the current size of the deck of cards. It will move the cards in the deck to the beginning of the vector. printVector - This function will receive two parameters: a vector and its dimension. The function will print the vector, and will print the values (the vector) of the initial hand, the updated deck, and the final hand. to make the code in c language Expected output :javascript only: Write a function `popularLetters(string)` that takes a string as an argument and returns an array of all of the characters that appear five or more times in the string.
