We want to find the shortest distance from a to z.
00:05
So what i'm going to do is start at a, and we're just going to look and see how we can get from a to z.
00:10
So i'm going to expand that picture a little bit, and i see that the shortest value is from a to c, which is 4.
00:18
So i'm going to go a to c, i would be 4.
00:21
And then from c, i can go 17 or 12.
00:24
So i'm going to go to f, which is going to be a value of 12.
00:30
Which now i've done 16, and now i can go from f to z, which is a total of 9 for a total of 25.
00:40
So we have now, so far, we have a distance of 25...
