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));
The Foreach loop iterates through the array and returns each value in the array until reaching the end of the array. What is the output of the following? $list = 0..00000000005 foreach ($item in $list) { Write-Output $item }

What does the following error message normally mean? IndexError: list index out of range Select one: а. This error normally indicates that you have tried to access an element of a list that doesn't exist. O b. This error normally means that you have used the range() function incorrectly. С. This error normally means that you have used a list where you should have used a tuple. d. This error normally means that you used too many lines of code in your program.

As part of this assignment, the program that you will be writing will store current grades in a dictionary using course codes as keys and with values consisting of percent grades in lists. The main functions of this program are to print a student's gradebook, to drop the lowest grade in each course, print the student's gradebook again, drop the course with lowest average, and finally printing the student's gradebook again. This program requires a main function and a custom value-returning function. In the main function, code these basic steps in this sequence (intermediate steps may be missing): start with an empty dictionary that represents a gradebook and then use a while loop to allow the input of course codes from the keyboard. End the while loop when the user presses enter without entering data.within the while loop:for each course entered, use a list comprehension to generate five random integers in the range of 70 through 100. These random integers in a list represent the…

Complete the method “readdata”. In this method you are to read in at least 10 sets of student data into a linked list. The data to read in is: student id number, name, major (CIS or Math) and student GPA. You will enter data of your choice. You will need a loop to continue entering data until the user wishes to stop. Complete the method “printdata”. In this method, you are to print all of the data that was entered into the linked list in the method readdata. Complete the method “printstats”. In this method, you are to search the linked list and print the following: List of student’s id and names who are CIS majors List of student’s id and names who are Math majors List of student’s names along with their gpa who are honor students (gpa 3.5 or greater) All information for the CIS student with the highest gpa (you may assume that different gpa values have been entered for all students) CODE (student_list.java) You MUST use this code: package student_list;import…
