Description

You are given an integer array coins of length n which represents the n coins that you own. The value of the ith coin is coins[i]. You can make some value x if you can choose some of your n coins such that their values sum up to x.

Return the maximum number of consecutive integer values that you can make with your coins starting from and including 0.

Note that you may have multiple coins of the same value.

 

Example 1:

Input: coins = [1,3]
Output: 2
Explanation: You can make the following values:
- 0: take []
- 1: take [1]
You can make 2 consecutive integer values starting from 0.

Example 2:

Input: coins = [1,1,1,4]
Output: 8
Explanation: You can make the following values:
- 0: take []
- 1: take [1]
- 2: take [1,1]
- 3: take [1,1,1]
- 4: take [4]
- 5: take [4,1]
- 6: take [4,1,1]
- 7: take [4,1,1,1]
You can make 8 consecutive integer values starting from 0.

Example 3:

Input: nums = [1,4,10,3,1]
Output: 20

 

Constraints:

  • coins.length == n
  • 1 <= n <= 4 * 104
  • 1 <= coins[i] <= 4 * 104

Solutions

Python3

class Solution:
    def getMaximumConsecutive(self, coins: List[int]) -> int:
        ans = 1
        for v in sorted(coins):
            if v > ans:
                break
            ans += v
        return ans

Java

class Solution {
    public int getMaximumConsecutive(int[] coins) {
        Arrays.sort(coins);
        int ans = 1;
        for (int v : coins) {
            if (v > ans) {
                break;
            }
            ans += v;
        }
        return ans;
    }
}

C++

class Solution {
public:
    int getMaximumConsecutive(vector<int>& coins) {
        sort(coins.begin(), coins.end());
        int ans = 1;
        for (int& v : coins) {
            if (v > ans) break;
            ans += v;
        }
        return ans;
    }
};

Go

func getMaximumConsecutive(coins []int) int {
	sort.Ints(coins)
	ans := 1
	for _, v := range coins {
		if v > ans {
			break
		}
		ans += v
	}
	return ans
}
