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
Function Description
Complete the plusMinus function in the editor below.
plusMinus has the following parameter(s):
- int arr[n]: an array of integers
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 .
Constraints
Output Format
Print the following lines, each to decimals:
- proportion of positive values
- proportion of negative values
- proportion of zeros
Sample Input
STDIN Function
----- --------
6 arr[] size n = 6
-4 3 -9 0 4 1 arr = [-4, 3, -9, 0, 4, 1]
Sample Output
0.500000
0.333333
0.166667

Моя варочная панель Bosch внезапно перестала работать. После обращения в московский сервисный центр мастер приехал уже на следующий день. Оказалось, что необходима замена управляющего модуля. Ремонт прошёл быстро и с использованием оригинальных запчастей, что гарантирует долгую службу панели. За качество ремонта мне предоставили гарантию на год. Стоимость работ оказалась весьма разумной, что не может не радовать.
