Richest Customer Wealth


Explanation
 Initialize
max_wealth
to 0, which will keep track of the maximum wealth found so far.  Iterate through each row in
accounts
, representing a customer’s bank accounts.  Compute the sum of each row, representing the total wealth for that customer.
 If the computed wealth is greater than the current
max_wealth
, updatemax_wealth
.  Return
max_wealth
as the final result, representing the wealth of the richest customer.

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
