You are given an `m x n` integer grid `accounts` where `accounts[i][j]` is the amount of money the ith customer has in the jth 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`
