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 6 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.
There are n=5 elements, two positive, two negative and one zero. Their ratios are 2/5 = 0.400000, 2/5 = 0.400000 and 1/5 = 0.200000. Results are printed as:
Complete the plusMinus function in the editor below.
plusMinus has the following parameter(s):
- int arr[n]: an array of integers
Print the ratios of positive, negative and zero values in the array. Each value should be printed on a separate line with 6 digits after the decimal. The function should not return a value.
The first line contains an integer,n , the size of the array.
The second line contains n space-separated integers that describe arr[n].
Print the following 3 lines, each to 6 decimals:
- proportion of positive values
- proportion of negative values
6 -4 3 -9 0 4 1
0.500000 0.333333 0.166667
