排列a包含N分子,其元素属于[0,N]之间,且不存在反复的元素.请你找出数组中缺失的元素(由于[0,N]之间有N+1个元素.而数组仅仅能存储N个元素.所以必定缺少一个元素).当中对数组的操作满足下列的条件:不能在常数时间内读取数组中的元素,可是可以读取数组中元素的某一个bit值.可以在常数时间内交换数组的两个元素的位置.请设计一种算法使其可以在线性时间内找出数组中缺失的元素. (N=2^k) An array a[] contains all of the integers from 0 to…
We define the smallest positive real number as the number which is explicitly greater than zero and yet less than all other positive real numbers except itself. The smallest positive real number, if exists, implies the existence of the second greater…
