For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }

The ArrayList is created using the following syntax: String[] array = {"red", "green", "blue"}; ArrayList list Display all the elements of this list using: a) foreach loop b) foreach method with lambda := new ArrayList(java.util.Arrays.asList(array));

PYTHON LAB: Inserting an integer in descending order (doubly-linked list) Given main.py and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insert_in_descending_order() method to insert new IntNodes into the IntList in descending order. Ex. If the input is: 3 4 2 5 1 6 7 9 8 the output is: 9 8 7 6 5 4 3 2 1 _____________________________________________________________________________________ Main.py: from IntNode import IntNode from IntList import IntList if __name__ == "__main__": int_list = IntList() input_line = input() input_strings = input_line.split(' ') for num_string in input_strings: # Convert from string to integer num = int(num_string) # Insert into linked list in descending order new_node = IntNode(num) int_list.insert_in_descending_order(new_node) int_list.print_int_list() IntNode.py class IntNode: def __init__(self, initial_data, next = None,...
