1672. Richest Customer Wealth

You are given an m x n integer grid accounts where accounts[i][j] is the amount of money the i​​​​​​​​​​​th​​​​ customer has in the j​​​​​​​​​​​th​​​​ bank. Return the wealth that the richest customer has.

A customer's wealth is the amount of money they have in all their bank accounts. The richest customer is the customer that has the maximum wealth.

 

Example 1:

Input: accounts = [[1,2,3],[3,2,1]]
Output: 6
Explanation:
1st customer has wealth = 1 + 2 + 3 = 6
2nd customer has wealth = 3 + 2 + 1 = 6
Both customers are considered the richest with a wealth of 6 each, so return 6.
Example 2:

Input: accounts = [[1,5],[7,3],[3,5]]
Output: 10
Explanation: 
1st customer has wealth = 6
2nd customer has wealth = 10 
3rd customer has wealth = 8
The 2nd customer is the richest with a wealth of 10.
Example 3:

Input: accounts = [[2,8,7],[7,1,3],[1,9,5]]
Output: 17
 

Constraints:

m == accounts.length
n == accounts[i].length
1 <= m, n <= 50
1 <= accounts[i][j] <= 100

这题很简单。。。

class RichestCustomerWealth : public Solution {
public:
    void Exec() {

    }
    int maximumWealth(vector<vector<int>>& accounts) {
        int maxWealth = 0;
        for (auto &banks : accounts) {
            maxWealth = std::max(maxWealth, std::accumulate(banks.begin(), banks.end(), 0));
        }
        return maxWealth;
    }
};
