Rank of all elements in an array

Question:

Given an array of N integers with duplicates allowed. All elements are ranked from 1 to N if they are distinct. If there are say x repeated elements of a particular value then each element should be assigned a rank equal to the arithmetic mean of x consecutive ranks.

Sample Input:

The first line of the input contains a single integer N size of the array. Next line contains N-Space separated integers, denoting elements of an array.

Output:

For each element of the array, print rank of that element .

Sample TestCase 1

Input :

• 3
• 20 30 10

Output :

• 2.0 3.0 1.0

Sample TestCase 2

Input :

• 7
• 1 2 5 2 1 60 3

Output :

• 1.5 3.5 6.0 3.5 1.5 7.0 5.0

Solution

package main
 
import "fmt"
 
func main() {
    var n int
    fmt.Scan(&n)
    ar := make([]int, n)
    ReadN(ar, 0, n)
 
    for j := 0; j < n; j++ {
        r := 1
        s := 1
        for k := 0; k < n; k++ {
            if (j != k) && (ar[k] < ar[j]) {
                r += 1
            }
            if (j != k) && (ar[k] == ar[j]) {
                s += 1
            }
        }
        fmt.Print(float32(float32(r) + float32(s - 1)/(float32(2))));
        fmt.Print(` `)
    }
}
 
func ReadN(all []int, i, n int) {
    if n == 0 {
        return
    }
    fmt.Scan(&all[i])
    ReadN(all, i+1, n-1)
}
