+    """
+    Sum of outcomes for rolling an N-sided dice K times.
+
+    This function returns a list. The first element is an array.
+    That array contains indexes.
+    The second element is another array.
+    That array contains probabilities for getting each index values
+    as the sum of obtained side values.
+
+     Algorithm Explanation:
+
+     1. Explanation of range:
+     When we are rolling a six-sided dice the range becomes
+     1 to 6.
+     While rolling 5 times range becomes 2 to 12.
+     The sum outcomes becomes 5 when all rolling finds 1.
+     30 happens when all rolling finds 6.
+     1 is the minimum and 6 is the maximum of side values
+     for a 6 sided dice. Therefore, the range is 5 to 30.
+     Therefore, the range is k to n*k.
+
+     2. Explanation of probability distribution:
+     Say we are rolling a six-sided dice 2 times.
+     for 0 roll, the outcome is 0 with probability 1.
+     For the first roll, the outcome is 1 to 6 equally distributed.
+
+     For the second roll, each previous outcome (1-6) will face
+     an addition from the second rolling (1-6).
+     If the first outcome is (known) 3, then the probability of
+     getting each of 4 to 9 will be 1/6.
+
+     The sum becomes 2 for two 1 outcomes. But the sum becomes
+     3 for two outcomes (1,2) and (2,1).

+
+     That phenomenon is the same as the convolution. However, the
+     index position is different. Therefore, we adjust the index.
+
+
+     NB: a) We are assuming a fair dice
+     b) Bernoulli's theory works with getting the probability of
+     exactly 3 sixes while rolling 5 times. It does not work directly
+     with the sum. The same sum can come in many combinations.
+     Finding all of those combinations and applying Bernoulli
+     is more computationally extensive.
+     c) The algorithm can be used in playing games where the sum of
+     multiple dice throwing is needed.
