Assume you have a square grid of known size and each spot in a grid as a number of some real value. If you start at the top left corner and can only go down or right, what it the maximum number you can obtain once you reach the bottom left?

Did you come across this question in an interview?

  • Assume you have a square grid of known size and each spot in a grid as a number of some real value. If you start at the top left corner and can only go down or right, what it the maximum number you can obtain once you reach the bottom left?
  • In a square matrix with each cell containing a numerical value, what algorithm would yield the maximum sum from top-left to bottom-right with only downward or rightward moves?
  • For a square grid filled with numbers, what path from the top-left to the bottom-right, moving only down or right, results in the largest sum?
  • Considering a grid with each position assigned a real number, what strategy ensures the highest cumulative value when moving from the top-left to the bottom-right corner, restricted to down or right movements?
  • With a square grid where each cell holds a value, how can you determine the greatest possible sum from the top-left corner to the bottom-right by moving only down or to the right?
  • On a square grid where each square has a specific value, what's the highest total you can achieve by traversing from the top left to the bottom right, if you can only move downwards or to the right?
  • In a grid with numerical values in each cell, what is the method to find the maximum possible value when traveling from the top-left to the bottom-right corner, moving only down or right?
  • When you have a square matrix where each entry is a number, how do you find the maximum sum path from the top left to the bottom right with restrictions to move only down or right?
  • If a square grid is populated with numbers at each spot, what is the maximum cumulative value obtainable when moving from the top left to the bottom right, given the movement is limited to down or right?
  • In a grid with numerical values assigned to each spot, what approach would you use to compute the highest sum from the top-left to the bottom-right corner, with the condition of moving only down or to the right?
  • Given a square grid with assigned numerical values, how would you calculate the maximum sum reachable by moving only down or right from the top left to the bottom right?
