$n$ points, write an algorithm to compute the closest pair points.
Given an array ofIn the figure above the closest pair of points have been marked in red. Given a set of points shown below, let $d$ be the distance between the closest pair of point. Then what is the value of $\left\lfloor 100d \right\rfloor$?
$S=\{(4,0), (6,2), (9,4), (8,9), (1,2), (3,5), (3, 1)\}$
Let the two closest points in the following set of coordinate points be $P_1=(x_1,y_1)$ and $P_2 = (x_2,y_2)$. What is the value of $x_1+y_1+x_2+y_2$?
Given a polygon $P$ and a point $p$ implement an algorithm to check whether the point lies inside the polygon or not.
The algorithm should output $1$ if the point is inside the polygon, and $0$ if it isn't. Consider the following pairs of polygon and point shown below, if $l_{n}$ in the value output by the algorithm for the $n$th pair of polygon and point, what is the value of the string $[l_{1}l_{2}l_{3}l_{4}]$?
$P_1=[(2, 1), (1, 3), (3, 3)], \\ p_1=(1,1)$
$P_2=[(2, 4), (4, 2), (6, 8), (8,6)], \\ p_2=(3,3)$
$P_3=[(5,2), (8,2), (8,4), (5,4)], \\ p_3=(6,1)$
$P_4= [(2,2), (2,2), (6,0), (6,0)], \\ p_4=(3,1)$
Details and assumptions
The points lying on the border of the polygon are considering to be inside the polygon
