(JAVA) InvertArrangement +invert(int[] a) : int [] +print(int[] a) : void Example 1: the invert method receives the following arrangement: [1,2,3,4,5] The invert method returns the array [5,4,3,2,1] Example 2: the print method receives the following array: [5,4,3,2,1] The print method prints: 5,4,3,2,1 (data separated by commas). TIP: for the print method use System.out.print () without the "ln".

USING a LOOP for C++ In this lab the completed program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. You should accomplish this using a for loop instead of a counter-controlled while loop. Instructions Write a for loop that uses the loop control variable to take on the values 0 through 10. In the body of the loop, multiply the value of the loop control variable by 2 and by 10....
