Write a program that reads a sequence of integers into a NumPy array and that computes the alternating sum of all elements in the array. For example, if the program is executed with the input data 14916974911 then it computes 14+916+97+49+11=2 Part-2 Write an application that computes the standard deviation of N real numbers. The standard deviation S is computed according to the following formula: s=N(x1x)2+(x2x)2++(xNx)2 The variable x is the average of N input values from x1 to xN. The program first prompts the user for N and then declares an array of size N. Then the program asks the user to enter the numbers and stores them in the array. After that, it calculates s by using this array and shows the result on the screen..
