In this post we will see how we can solve this challenge in Java Given a 2D Array, 1 1 1 0 0 0 0 1 0 0 0 0 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 . Hackerrank Solutions. Complete the function hourglassSum in the editor below. It has the advantage to not run through the array a second time and instead calculate the results as soon as the data to do it is available. When we sum the integers and, we get the integer. after this steps convert them to string and check if they are equel. I created almost all solutions in 4 programming languages – Scala, Javascript, Java and Ruby. As expected, both of these were the fastest, but what I didn't expect to see was that solution 1 had a distinct advantage over #2. There are some really good solutions in this thread, but I wanted to throw out some variations in case anyone else was curious about how Java performed using different constructs. Please read our, // Approach 1: explicitly add the array values (TIED FASTEST), // Approach 2: Inner loop to sum top/bottom rows (2ND FASTEST), // Approach 3: Use streams to sum top/bottom rows (2ND SLOWEST), // Approach 4: Use stream to loop/sum rather than for loops (SLOWEST). ; Sort the prices array in ascending order so that combination of minimum difference can be found by comparing adjacent prices. The hourglass possessing the largest sum is: int top = arr[i][x]+arr[i][x+1]+arr[i][x+2]; int bottom = arr[i+2][x]+arr[i+2][x+1]+arr[i+2][x+2]; if(top+middle+bottom>sum){sum=top+middle+bottom;}.
