It's Christmas time, happiest time of the whole year. But Sandy is not happy because her mother isn't with her. She wrote a letter to Santa Claus and wished to see her mother. Since Santa has no address, she thought the only way to send the letter was to make it a paper plane and throw hoping that it will reach to Santa. She threw the paper plane but letter must travel much more farther away. Can you help the letter to reach Santa Claus?
