Consider the following C declaration: struct Si (char a; int b; ) struct S2 (float a; double b; union U struct Si sl; struct S2 s2; Assume the machine has 1-byte characters, 4-byte integers, 8-byte floating numbers, and 16-byte double- precision floating numbers. Assume the compiler does not reorder the fields, and it leaves no holes in the memory layout. How many bytes does u occupy? If the memory address of u starts from 1000, what are the start addresses of u·s1.b and u . s2.b?

Write a method named addall that could be placed inside the hashintset class. this method accepts another hashintset as a parameter and adds all elements from that set into the current set, if they are not already present. for example, if a set s1 contains [1, 2, 3] and another set s2 contains [1, 7, 3, 9], the call of s1.addall(s2); would change s1 to store [1, 2, 3, 7, 9] in some order. you are allowed to call methods on your set and/or the other set. do not modify the set passed in. this method should run in o(n) time where n is the number of elements in the parameter set passed in.

Ihave a singular monitor that is a tv for my computer. recently, i took apart my computer and put it back together. when i put in the hdmi cord and booted the computer to see if it worked, the computer turned on fine but the screen was blue with "hdmi no signal." i've tried everything that doesn't require buying spare parts, any answer is appreciated!
