# 1672. Richest Customer Wealth

#### Easy

***

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`

```python
class Solution:
    def maximumWealth(self, accounts: List[List[int]]) -> int:
        result = 0
        for i in range(len(accounts)):
            temp = 0
            for j in range(len(accounts[0])):
                temp += accounts[i][j]
            result = max(result, temp)
        return result
```
