Problem Statement

You are given an m x n matrix 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.

Imagine every customer has multiple bank accounts, with each account holding a certain amount of money. The total wealth of a customer is calculated by summing all the money across all their multiple.

Examples

1. Example 1:

   • Input: accounts =

     [[5,2,3],
      [0,6,7]]
     

   • Expected Output: 13
   • Justification: The total wealth of the first customer is 10 and of the second customer is 13. So, the output is 13 as it's the maximum among all customers.

2. Example 2:

   • Input: accounts =

     [[1,2],
      [3,4],
      [5,6]]
     

   • Expected Output: 11
   • Justification: Total wealth for each customer is [3, 7, 11]. Maximum of these is 11.

3. Example 3:

   • Input: accounts =

    [[5,10,15],
     [10,20,30],
     [15,30,45]]
   

   • Expected Output: 90
   • Justification: Total wealth for each customer is [30, 60, 90]. The wealthiest customer has 90.

Constraints:

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