Problem Statement : Given an array of integers, find the sum of its elements. Function Description It must return the sum of the array elements as an integer. simpleArraySum has the following parameter(s): ar : an array of integers Input Format The first line contains an integer, n, denoting the size of the array. The second line contains, n, space-separated integers representing the array's elements. Output Format Print the sum of the array's elements as a single integer. Sample Input 6 1 2 3 4 10 11 Sample Output 31 Program: public class Sum{ public static void main(String[] args) { int [] arr = {1,2,3,4,10,11,749}; int length=arr.length; int sum=0; for(int i=0;i<length;i++){ sum += arr[i]; } System.out.println(sum); } }
Problem statement : Given an array of integers, calculate the ratios of its elements that are positive , negative , and zero . Print the decimal value of each fraction on a new line with places after the decimal. Note: This challenge introduces precision problems. The test cases are scaled to six decimal places, though answers with absolute error of up to are acceptable. Example There are elements, two positive, two negative and one zero. Their ratios are , and . Results are printed as: 0.400000 0.400000 0.200000 Print Print the ratios of positive, negative and zero values in the array. Each value should be printed on a separate line with digits after the decimal. The function should not return a value. Input Format The first line contains an integer, , the size of the array. The second line contains space-separated integers that describe . Sample Input 6 -4 3 -9 0 4 1 Sample Output 0.500000 0.333333 0.166667 Explanation There are positive numbers,
