+### MaxSpan
+
+Consider the leftmost and righmost appearances of some value in an array.
+We'll say that the "span" is the number of elements between the two inclusive.
+A single value has a span of 1. Returns the largest span found in the given array.
+
+```
+maxSpan([1, 2, 1, 1, 3]) → 4
+maxSpan([1, 4, 2, 1, 4, 1, 4]) → 6
+maxSpan([1, 4, 2, 1, 4, 4, 4]) → 6
+```
