Recovering 3-D structure from motion in noisy 2-D images is a problem addressed by many vision system researchers. By consistently tracking feature points of interest across multiple images using a methodology first described by Lucas-Kanade, a 3-D shape of the scene can be reconstructed using these features points using the factorization method developed by Tomasi-Kanade.
樣板 B 樹 ( B - tree )
規則 :
(1) 每個節點內元素個數在 [MIN,2*MIN] 之間, 但根節點元素個數為 [1,2*MIN]
(2) 節點內元素由小排到大, 元素不重複
(3) 每個節點內的指標個數為元素個數加一
(4) 第 i 個指標所指向的子節點內的所有元素值皆小於父節點的第 i 個元素
(5) B 樹內的所有末端節點深度一樣

A . int $e,a,b=10
B. char c,d=’a’
C. float e=0.0d
D. double c=0.0f
給定兩個集合A、B，集合內的任一元素x滿足1 ≤ x ≤ 109，并且每個集合的元素個數不大于105。我們希望求出A、B之間的關系。
任 務 ：給定兩個集合的描述，判斷它們滿足下列關系的哪一種：
A是B的一個真子集，輸出“A is a proper subset of B”
B是A的一個真子集，輸出“B is a proper subset of A”
A和B是同一個集合，輸出“A equals B”
A和B的交集為空，輸出“A and B are disjoint”
上述情況都不是，輸出“I m confused!”
We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.
