+"""
+Pure Python implementation of the jump search algorithm.
+This algorithm iterates through a sorted collection with a step of n^(1/2),
+until the element compared is bigger than the one searched.
+It will then perform a linear search until it matches the wanted number.
+If not found, it returns -1.
