Lab Assignment $2$ i want this using Java make a clear code and please be fast i have no time and explain the code

In the $8-$puzzle problem, the final goal is

$\backslash$table$[[1,2,3],[4,5,6],[7,8,]]$

Make a function that can return the heuristic functions $h_1,h_2$ and $h_3$ for any node. For the details of the heuristic functions, please see the course slides.

Use the functions developed above that can return the heuristic functions $h_1,h_2$ and $h_3$ for any node, write program for greedy best first search to find the goal node of $8-$puzzle problem. Discuss and compare the effect of h$1$ h$2$ and h$3$ on time and space complexity.

Submission:

$($i$)$ Working code

$($ii$)$ Description of effect of h$1,$ h$2,$ h
