Given an array of integers, calculate which fraction of the elements are positive, negative, and zeroes, respectively. Print the decimal value of each fraction. Input Format The first line, NN, is the size of the array. The second line contains NN space-separated integers describing the array of numbers (A1,A2,A3,⋯,ANA1,A2,A3,⋯,AN). Output Forma…
