I just added an input with a, This problem is a classic example of dynamic programming. Then the double-array of triangle can be processed in order using a simple for loop, as opposed to in reverse using a slightly more complicated for loop. Practice your skills in a hands-on, setup-free coding environment. Not the answer you're looking for? Here they are (without prime cache). In the Pern series, what are the "zebeedees"? In order to accomplish this, we'll just need to iterate backwards through the rows, starting from the second to the last, and figure out what the best path to the bottom would be from each location in the row. Toggle some bits and get an actual square. From 4, you can move to 5 or 1 but you can't move to 6 from 4 because it is not adjacent to it.Similarly from 1, in the third row, you can move to either 2 or 5 but you can't move to 1 in the fourth row (because it is not adjacent).I am sure you have got the problem now, let's move to solving it now in this video of Joey'sTech.-------------------Also Watch--------------------- 1. As this was brought back up, it's worth pointing out that the dynamic programming technique discussed in answers and comments can be done very simply with a reduceRight: At each step we calculate the minimum paths through all the elements in a row. }.

If we should left shift every element and put 0 at each empty position to make it a regular matrix, then our problem looks like minimum cost path. I'm confused how it should equal -1, because -1 + 2 = 1 and none of the numbers in third array equal -1 when summed with 1. In this problem, the condition is that you can move down to adjacent numbers only. The ToArray2D converts the parsed numbers/values into a two-dimensional array. If we do this, however, we'll need to write extra code to avoid going out-of-bounds when checking the previously completed rows of the DP array.
