+/* 
+    Bubble sort is a recursive algorithm based on swapping 2 values closest to each other: k and k+1
+    We start by checking the first two values of the array, and we swap them if the first value is bigger than the second one.
+    Then we recursively swap the second value with the third, if needed and so on until the array is sorted.
+    Average Time Complexity: O(n^2))
