The Nineteenth Byte

Given (on STDIN, as command line arguments, or as function arguments) two distinct non-empty strings, find and return the shortest substring of the first string which is not a substring of the second. If no such substring exists, you may return the empty string, return any string which isn't a su...

TILA steradians:

Steradian

The steradian (symbol: sr) or square radian is the SI unit of solid angle. It is used in three-dimensional geometry, and is analogous to the radian which quantifies planar angles. The name is derived from the Greek stereos for "solid" and the Latin radius for "ray, beam". The steradian, like the radian, is a dimensionless unit, essentially because a solid angle is the ratio between the area subtended and the square of its distance from the vertex: both the numerator and denominator of this ratio have dimension length squared (i.e. L2/L2 = 1, dimensionless). It is useful, however, to distinguish...

@KennyLau Most cycle detection algorithms will fail on this because they generally assume that one number will always be followed by the same number. Your sequence, for example, has 3s followed by a 1 and a 5, which the tortoise and hare algorithm will fail on because it's not designed for this kind of cycle detection.
