Steps

  1. Take 2 variable max=0, sum=0
  2. Run a for loop.
  3. In each row calculate the sum of all element.
  4. If the sum > max, then max = sum.
  5. Set the sum = 0;

Java Code



class Solution {
public int maximumWealth(int[][] accounts) {
int max = 0;
int sum = 0;

    for(int i = 0; i< accounts.length; i++){
        for(int j = 0; j < accounts[i].length; j++){
            sum += accounts[i][j];
        }
        if(max < sum){
            max = sum;
        }
        sum = 0;
    }
    return max;
}

Great read:

Is it Time to go Back to the Monolith?

History repeats itself. Everything old is new again and I’ve been around long enough to see ideas discarded, rediscovered and return triumphantly to overtake the fad. In recent years SQL has made a tremendous comeback from the dead. We love relational databases all over again. I think the Monolith will have its space odyssey moment again. Microservices and serverless are trends pushed by the cloud vendors, designed to sell us more cloud computing resources.

Microservices make very little sense financially for most use cases. Yes, they can ramp down. But when they scale up, they pay the costs in dividends. The increased observability costs alone line the pockets of the “big cloud” vendors.
