Consider the array of floating-point values called "measurements". Complete the code so it would display the values from "measurements" that deviate from TARGET by no more than TOLERANCE. You may want to use Math static method "abs", which returns the absolute value of a given number. For example, Math.abs(-3) = 3. To be clear, the expected output of your program should be the numbers 3.51, 3.49, 3.51, and 3.5. double measurements[] = { 3.51, 3.53, 3.49, 3.51, 3.47, 3.50 };...

Consider the array of double values called "measurements". Complete the code so it would display on the console the values from "measurements" that deviate from TARGET by no more than TOLERANCE. You may want to use Math static method "abs", which returns the absolute value of a given number or expression. For example, if double variable measure = 2.9, then Math.abs(measure - 3) = 0.1..

C++ Make a prototype, including task, input and output, of mergeLists that would take two lists of reference (ArrayList) and return a merged list as in alternating adding items from each list (i.e. position 1 from list 1, position 1 from list 2, position 2 from list 1, position 2 from list 2, and so on). Note, do NOT code the function.
