发帖数: 169 | 1 After 10 jumps, the horse could cover an octagon shaped area. The vertices
of this octagon is located at (+/-10, +/-20), (+/-20, +/-10).This is twelve
10by10 squares and four half squares. So, the area is 1400.However, every
time the horse jumps, the color where it lands alternate, the horse
therefore could only lands on the same color as it starts after even number
of jumps. This havles the number of squares where it could land. ~700 should
be the answer. |
