+Task 1: Third Maximum
+Submitted by: Mohammad Sajid Anwar
+
+You are given an array of integers, @ints.
+
+Write a script to find the third distinct maximum in the given array.
+If third maximum doesn’t exist then return the maximum number.

+Task 2: Jumbled Letters
+Submitted by: Ryan Thompson
+
+An Internet legend dating back to at least 2001 goes something like this:
+
+|| Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn’t mttaer in waht
+|| oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist
+|| and lsat ltteer be at the rghit pclae. The rset can be a toatl mses and you
+|| can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not
+|| raed ervey lteter by istlef, but the wrod as a wlohe.
+
+This supposed Cambridge research is unfortunately an urban legend. However, the
+effect has been studied. For example—and with a title that probably made the
+journal’s editor a little nervous—Raeding wrods with jubmled lettres: there is a
+cost by Rayner, White, et. al. looked at reading speed and comprehension of
+jumbled text.
+
+Your task is to write a program that takes English text as its input and outputs a
+jumbled version as follows:
+
+1) The first and last letter of every word must stay the same
+2) The remaining letters in the word are scrambled in a random order
+   (if that happens to be the original order, that is OK).
+3) Whitespace, punctuation, and capitalization must stay the same
+4) The order of words does not change, only the letters inside the word
+
+So, for example, “Perl” could become “Prel”, or stay as “Perl,” but it could not
+become “Pelr” or “lreP”.

+
+say jumbledLetters(<<EOT); 
+According to a research at Cambridge University, it doesn't matter in what order
+the letters in a word are, the only important thing is that the first and last
+letter be at the right place. The rest can be a total mess and you can still
+read it without problem. This is because the human mind does not read every
+letter by itsel, but the word as a whole.
