[LeetCode] Remove Duplicates from Sorted Array II
Follow up for "Remove Duplicates": What if duplicates are allowed at most twice?
For example, Given sorted array A = [1,1,1,2,2,3]
,
Your function should return length = 5
, and A is now [1,1,2,2,3]
.
class Solution {public: int removeDuplicates(int A[], int n) { vector<int> Acopy(A,A+n); if(n<=2) return n; int res = n; int temp = A[0]; int tempNum = 1; int j = 1; for(int i=1;i<n;i++){ if(Acopy[i]==temp && tempNum<2){ A[j++]=Acopy[i]; tempNum++; }else if(Acopy[i]==temp && tempNum>=2){ tempNum++; res--; }else if(Acopy[i]!=temp){ temp = Acopy[i]; tempNum = 1; A[j++]=Acopy[i]; } }//end for return res; }};
关键数组A中的前res个元素要变化成需要的结果。
