Given an array A of n integers, a leader element of the array A is the element that appears more than half of the time in A. Using one stack, implement in Java an O(n) running time complexity method static int leader(int[] A) to find a leader element and return the index (any) of the leader in A. The program must returns -1 if no leader element exists. Examples:int[] a = {23, 23, 67, 23, 67, 23, 45}; > leader(a) = 6int[] a = {23, 24, 67, 23, 67, 23, 45}; > leader(a) = -1

17. implement the jvm dload instruction for the mic-2. it has a 1-byte index and pushes the local variable at this position onto the stack. then it pushes the next higher word onto the stack as well

This first part of the film shows the early history of motion pictures. how accurate do you think the portrayal of the early motion picture industry is? why? is historical accuracy important in films and theatre productions? explain. in the scene where don is going to the party (starting at time code 14: 51), we see a street scene as he first rides with cosmo and then with kathy. what aspects did the filmmaker include to make the scene look and feel like don, cosmo, and kathy are riding in a car on a street? think about elements such as scenery, sound, props, lighting, and so on. a "talkie" picture is shown starting around time code 21: 15. how does the audience in the film react to the "talkie"? what influence do audiences have on film and theatre performances? how do film and theatre actors influence audiences? in the musical scene with cosmo (starting at time code 27: 00), how does the actor use props? what is the result? do you think the use of props effectively fulfilled the artistic vision for this musical number? why or why not?

How would you categorize the software that runs on mobile devices? break down these apps into at least three basic categories and give an example of each.
