问题描述:一个有序序列经过反转,得到一个新的序列,查找新序列的某个元素.12345->45123. 算法思想:利用二分查找的思想,都是把要找的目标元素限制在一个小范围的有序序列中.这个题和二分查找的区别是,序列经过mid拆分后,是一个非连续的序列.特别要注意target的上下限问题.因为是非连续,所以要考虑上下限,而二分查找,序列式连续的,只用考虑单限.有递归算法和迭代算法. 递归算法: public int search(int[] nums, int target) { return bin
list_one=[3,6,2,17,7,33,11,7] list_two=[1,2,3,7,4,2,17,33,11] list_new=list_one+list_two list=[] i=0 for x in list_new : if x not in list : list.append(x) list.sort() print list
Special binary strings are binary strings with the following two properties: The number of 0's is equal to the number of 1's. Every prefix of the binary string has at least as many 1's as 0's. Given a special string S, a move consists of choosing two
