You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 1846. Maximum Element After Decreasing and Rearranging.go
    path of file: ./repos/LeetCode-Go/leetcode/1846.Maximum-Element-After-Decreasing-and-Rearranging
    
    the code of the file until where you have to start completion: package leetcode

func maximumElementAfterDecrementingAndRearranging
    
func maximumElementAfterDecrementingAndRearranging(arr []int) int {
	n := len(arr)
	count := make([]int, n+1)
	for _, v := range arr {
		count[min(v, n)]++
	}
	miss := 0
	for _, c := range count[1:] {
		if c == 0 {
			miss++
		} else {
			miss -= min(c-1, miss)
		}
	}
	return n - miss
}
