These two questions are interesting, because the elements are 1~n, so the value of each element-1 (mapped to 0~n-1) can be directly used as subscript. This will be nums in the corresponding subscript element *-1 with I means index+1 this element has appeared, can save storage space.448.

title : An integer array satisfies 1Ideas : see many netizens say with set data structure to do, this violates the space complexity requirements, so sort or to do local. Iterate the array, put this number where it should be: for example, a[0]=4, then we put 4 to a[3], and then put the a[3] place 7 to a[6] place, place a[6] Place 3 a[2] place, put a[2] place 2 at a[1] Place, Dizzy BarDo this:Step1: 7, 3,2,4, 8,2,3,1Step2:3, 3,2,4,8,2,7, 1Step3:2, 3,3, 4,8,2,7,1Step4:3,2, 3,4,8,2,7,1Step4. 1: Now

Given an input string, reverse the string word by word. For Example,given s = "The Sky is Blue" and return "Blue is Sky the".

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 The does not appear in this array.Could do it without extra space and in O (n) runtime? Assume the returned list does not count as extra space.Example:input:[4,3,2,7,8,2,3,1]output:[5,6]Solution:Mark the value of already apeared index to negative and then loop it through to find the positive ones and then the index of PO Sitive ones is the re

because of the sort, the time complexity is O (NLOGN), does not satisfy the question O (n), therefore this method still is not OK.3. Because all of the numbers in the array are greater than or equal to 1 and less than or equal to N, and N is the length of this condition. So you can mark which numbers appear as an array subscript as an index, and mark the number as negative if the number corresponding to the subscript appears. Calculates the subscript form of the number x appearing in t
