Leetcode#80 Remove Duplicates from Sorted Array II
简单模拟题。
从先向后遍历,如果重复出现2次以上,就不移动,否则移动到前面去
代码:
1 int removeDuplicates(int A[], int n) { 2 if (n == 0) return n; 3 4 int len = 1; 5 int dupSum = 1; 6 7 for (int i = 1; i < n; i++) { 8 if (A[i] == A[i - 1]) { 9 dupSum++; 10 } 11 else 12 dupSum = 1; 13 if (dupSum <= 2) { 14 A[len] = A[i]; 15 len++; 16 } 17 } 18 19 return len; 20 }
