Every time new member joins the Team PWC, I get very excited. With time, I started to feel I know him/her so well. There is one more thing that excites me, is when I see an existing member coming back after the break. Sometimes they even contribute to past challenges. Not just only code contribution but writes blog as well. You know who I am talking about.

Last but not the least, I woud like to thank each and every member for their support and encouragement.

TASK #1

Merge Intervals

Write a script to merge the given intervals where ever possible.

[2,7], [3,9], [10,12], [15,19], [18,22]

The script should merge [2, 7] and [3, 9] together to return [2, 9].

Similarly it should also merge [15, 19] and [18, 22] together to return [15, 22].

The final result should be something like below:

[2, 9], [10, 12], [15, 22]

TASK #2

Contributed by Ryan Thompson.

Noble Integer

You are given a list, @L , of three or more random integers between 1 and 50. A Noble Integer is an integer N in @L , such that there are exactly N integers greater than N in @L . Output any Noble Integer found in @L , or an empty list if none were found.

An interesting question is whether or not there can be multiple Noble Integers in a list.

For example,

Suppose we have list of 4 integers [2, 6, 1, 3].

Here we have 2 in the above list, known as Noble Integer, since there are exactly 2 integers in the list i.e.3 and 6, which are greater than 2.

Therefore the script would print 2.
