A simple path is an ordered route from a starting location to an ending location, described by the relative positions and movements needed to follow it, such as up, down, left, right, forward, backward, or a turn, often on a picture or simple grid. The description identifies each successive location and can be reversed to trace the route back; coordinate notation, scale, distance calculations, and complex routes are beyond this understanding.
A path tells where to start, which way to move, and where to stop. Read the movements in order, one at a time.
Look at this simple grid:
┌───────┬───────┬───────┐
│ START │ │ │
├───────┼───────┼───────┤
│ │ │ END │
└───────┴───────┴───────┘
Example: Describe the path from START to END.
So, the path is:
Start → right → right → down → End
To check the path, trace it backward from END:
End → up → left → left → Start
The directions are reversed because you are walking back along the same route.
