1. write a complete program based on

public static double stdev(int[] array){ int sum = 0; for(int i = 0; i

rite a method called stdev that returns the standard deviation of an array of integers. Standard deviation is com- 6. W by taking the square root of the sum of the squares of the differences between puted divided by one less than the number of elements. (It's just that simple!) More concisely and mathematically, the standard deviation of an array a is written as follows each element and the mean., a.length-1 (a[i] -average(a)) stdev(a) - a.length 1 For example, if the array passed contains the values [1, -2, 4, -4, 9, -6, 16, -8, 25, -101. your method should return approximately 11.237 in traer k and an array a as its parameters and returns the ele
