LeetCode: Richest Customer Wealth Leetcode Solution

Difficulty: Easy

The Richest Customer Wealth problem on LeetCode is a simple array problem. The task is to find the maximum wealth among a group of customers, where the wealth of a customer is the sum of their bank account balances.

To solve this problem, you can iterate over the 2D array of bank account balances and calculate the sum of each customer's wealth. Then, you can keep track of the maximum wealth that you have seen so far and return it as the final solution.

Here is the detailed solution for the Richest Customer Wealth problem:

- Initialize a variable
`max_wealth`

to 0. - Iterate over the rows of the 2D array
`accounts`

. - For each row, initialize a variable
`wealth`

to 0. - Iterate over the columns of the current row and add each balance to
`wealth`

. - If
`wealth`

is greater than`max_wealth`

, update`max_wealth`

to`wealth`

. - After iterating over all rows, return
`max_wealth`

.

Here is the code implementation of the solution in Python:

```
class Solution:
def maximumWealth(self, accounts: List[List[int]]) -> int:
max_wealth = 0
for row in accounts:
wealth = 0
for balance in row:
wealth += balance
max_wealth = max(max_wealth, wealth)
return max_wealth
```

The time complexity of this solution is O(m * n), where m is the number of rows and n is the number of columns in the 2D array. The space complexity is O(1) as we only use constant extra space to keep track of `max_wealth`

and `wealth`

.
