今天来总结一下Missing Number一系列问题 1、Find All Numbers Disappeared in an Array Given an array of integers where 1 ≤ a[i] ≤n(n= size of array), some elements appear twice and others appear once. Find all the elements of [1,n] inclusive that do not appear in this array. Could ...
Given an array containingndistinct numbers taken from0, 1, 2, ..., n, find the one that is missing from the array. For example, Givennums=[0, 1, 3]return2. Note: Your algorithm should run in linear runtime complexity. Could you implement it using only constant extra space complexity?
