A "drunkard's walk" involves an individual wandering from the origin in $3$D space,

represented by the coordinates $(0,0,0).$ With each step they take, they move randomly in one of six

possible directions: north $($positive y$-$axis$),$ south $($negative y$-$axis$),$ east $($positive x$-$axis$),$ west

$($negative x$-$axis$),$ up $($positive z$-$axis$),$ or down $($negative z$-$axis$),$ each with a $1/6$ probability. As

the individual takes more steps, they must remember where they started and continue moving

randomly.

The objective is to determine how far the individual will be from the starting point $(0,0,0)$ after

taking N number of steps. We can create a C program to simulate this random walking motion in

$3$D for N steps. This program should ask the user to input an integer representing the number of

steps to be taken. It should work for any positive value of steps, even for a large number. However,

the program should display an error message if the user enters an invalid number $($such as a

negative value or zero$).$ After each step, the program should show the current $3$D coordinates of

the random walker with respect to the origin $(0,0,0).$ Finally, when the random walker has

completed all the steps, the program should calculate and display the squared distance from the

origin, which is determined by the formula x

$2+$y$2+$z$2$
