Write a function, which finds the element of an array x, which is nearest to a given number a. The function must have a one-dimensional array and a number as inputs. The outputs must include: the value of the element of x closest to a, the index of this element within the array, and the distance between this element and a. Hint: to find the nearest element, compute the absolute value x(i) - al and find for which x(i) it is the smallest. Please run the function for the array x = [0.1, 25, 11.2, -11.1, 8.88, 21,-0.5,-10, 7.1] and the number a 9.
