<li><strong>] PROBLEM - remove CRYSTAL COMPOUNDS from workbench of CRYSTALS</strong></li>
<ol>
<li>]<strong> </strong>single player word game, take elemental crystals (repped by letters) and forms compounds,&nbsp;</li>
<li>] each crystal is a specific type of element, F I Z B A R&nbsp;</li>
<li>] crystals are presented in a line</li>
<li>] COMPOUNDS form when adjacent crystals are in a specific order, FIZ, BAR, BAZ, ZIF, RAB, ZAB, ( last 3 are first 3 reversed)</li>
<li>] IF adjacent CRYSTALS form a SEQUNCE ex BAZIF consisting of overlapping COMPOUNDS ( BAZ ZIF ), then sequences is LARGER COMPOUND&nbsp;</li>
<li>] when compound forms, crystals are removed from the workbench, any crystals to their right, slide left, so there are no gaps.&nbsp;</li>
<li>] after sliding left, check again, for compounds</li>
<li>*] ASSUME no compounds exist on workbench at start of the game&nbsp;</li>
<li>] PLAYER - can only re-arragange crystals by swapping adjacent crystals , CAN only swap if crystals if a COMPOUND formed is the result (legal move)</li>
<li>] if PLAYER MOVE is !legal, no crystals are swapped</li>
<li>] gameplay alternates between ] removeCompound, ] slideLeft, ] player making swap&nbsp;</li>
</ol>
<li><strong>] INPUTS -</strong>&nbsp;</li>
<ol>
<li>] line 1 int C, ( 0 &lt; C &lt; 100) number of crystals on the workbench</li>
<li>] line 2 str C capital letters, ith letter = i-th crystal&nbsp;</li>
<li>] line 3 int S ( 0 &lt;=S &lt; 50) number of swaps the player makes</li>
<li>] line 4 S space seperated integers , index of the left letter, to be swapped with its right , leftmost crystal is 0&nbsp;</li>
</ol>
<li><strong>] PROCESS -&nbsp;</strong></li>
<ol>
<li>] get inputs&nbsp;</li>
<li>] removeCompound&nbsp;</li>
<li>] slideLeft (shrinkLeft)&nbsp;</li>
<li>] playerSwap</li>
</ol>
<li><strong>] OUTPUT -&nbsp;</strong></li>
<ol>
<li>] from left to right, letters of the crystals remaining on the workbench, AFTER the swaps are done ANY any compounds are removed,&nbsp;</li>
<li>] written to stdout&nbsp;</li>
</ol></ol>
