+===============================================>    Candlelight     <======================================================
+
+Given an integer representing the number of candles you start with, and an integer representing how many burned candles it takes to create a new one, return the number of candles you will have used after creating and burning as many as you can.
+
+For example, if given 7 candles and it takes 2 burned candles to make a new one:
+
+Burn 7 candles to get 7 leftovers,
+Recycle 6 leftovers into 3 new candles (1 leftover remains),
+Burn 3 candles to get 3 more leftovers (4 total),
+Recycle 4 leftovers into 2 new candles,
+Burn 2 candles to get 2 leftovers,
+Recycle 2 leftovers into 1 new candle,
+Burn 1 candle.
+You will have burned 13 total candles in the example.
+
+===========================================================================
+O/P :
+1. burn_candles(7, 2) should return 13
+2. burn_candles(10, 5) should return 12
+3. burn_candles(20, 3) should return 29
