# 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

## Solutions

```cpp
class Solution {
public:
    int maximumWealth(vector<vector<int>>& accounts) {
        int res = 0;
        for (int i = 0; i < accounts.size(); i++) {
            auto sum = accumulate(accounts[i].begin(), accounts[i].end(), 0);
            res = max(res, sum);
        }
        return res;        
    }
};
```
