John's laptop won't recharge and he suspects the ac adapter is the problem. which tool should he use to test it?

Var add = function( x, y ) { return ( x + y ); } alert( add (5, 3) ); 11. (refer to code example 2.) the function a. accepts 2 parameters and returns 2 values. b. accepts 2 parameters and returns 1 value. c. accepts 2 parameters and does not return a value. d. does not accept a parameter and returns 1 value.

Write a program called assignment3 (saved in a file assignment3.java) that computes the greatest common divisor of two given integers. one of the oldest numerical algorithms was described by the greek mathematician, euclid, in 300 b. c. it is a simple but very e↵ective algorithm that computes the greatest common divisor of two given integers. for instance, given integers 24 and 18, the greatest common divisor is 6, because 6 is the largest integer that divides evenly into both 24 and 18. we will denote the greatest common divisor of x and y as gcd(x, y). the algorithm is based on the clever idea that the gcd(x, y) = gcd(x ! y, y) if x > = y and gcd(x, y) = gcd(x, y ! x) if x < y. the algorithm consists of a series of steps (loop iterations) where the “larger” integer is replaced by the di↵erence of the larger and smaller integer. this continues until the two values are equal. that is then the gcd.

Describe a data structures that supports the stack push and pop operations and a third operation findmin, which returns the smallest element in the data structure, all in o(1) worst-case time.
