In а nоn-cyclic grid wоrld, аssume the rоbot cаn move up, down, left, and right one grid space at a time. The starting location is (0, 0) (top left), and there are no additional barriers or walls inside the grid. Note: There are no squares with negative coordinates in the grid.In BFS (Breadth First Search), a list of nodes (called LST) is used to maintain the priority of the search. Nodes are added to LST during exploration as dictated by BFS. How many nodes are in LST after completely expanding both (0,1) and (1,0)?
