1672. Richest Customer Wealth

🟩 Easy

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.

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

Hint-1

Calculate the wealth of each customer

Hint-2

Find the maximum element in array.

Solution

My Solution

func maximumWealth(accounts [][]int) int {
    max := 0
    for _, i := range accounts {
        sum := 0
        for _,j := range i {
            sum+=j
        }
        if sum > max {
            max = sum
        }
    }
    return max
}
