+## 45. 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. For example:
+
+```
+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.
+```
+
+```js
+const maximumWealth = accounts => {
+   // Your solution
+};
+
+console.log(maximumWealth([[2,8,7],[7,1,3],[1,9,5]]));  // 17
+console.log(maximumWealth([[1,5],[7,3],[3,5]]));        // 10
+console.log(maximumWealth([[1,2,3],[3,2,1]]));          // 6
+```
