A bear is in the center of the left-down corner of a $100 \times 100$ grid. A bear cycle is defined as a cycle that visits each square exactly once and returns to the starting point. By removing a row or column, the bear cycle is divided into several paths. Determine the minimum value of $k$ such that, for any bear cyc...

A bee can fly or walk in a straight line between any two corners on the inside of a cubic box of length 1. The bee managed to move so that it visited every corner of the box without passing through the same point twice in the air or on the wall of the box. What is the largest possible length of such a path?

A bee flies 10√2 meters in the direction 45° clockwise of North (that is, in the NE direction). Then, the bee turns 135° clockwise, and flies 20 meters forward. It continues by turning 60° counterclockwise, and flies forward 14 meters. Finally, the bee turns 120° clockwise and flies another 14 meters forward before fin...

A bee is moving in three-dimensional space starting at the point $(0, 0, 0)$. A fair six-sided die with faces labeled $A^+, A^-, B^+, B^-, C^+$, and $C^-$ is rolled four times.
