Return the final string after all such duplicate removals have been made. It is guaranteed the answer is unique. Example 1: Input:"abbaca" Output:"ca" Explanation: For example, in "abbaca" we could remove "bb" since the letters are adjacent and equal, and this is the only possible mov...

这个题目是LeetCode上的一道题,要求在一个已排序的链表中删除重复的元素。这个问题可以通过使用两个指针来解决,一个指向当前元素,另一个指向下一个元素。当遇到重复的元素时,将第二个指针向前移动一位。这样,我们就可以在遍历过程中删除重复的元素。以下是C语言实现的代码:```c...
Solved: Hello, I have in a column, values including some duplicates : Ex : Input : ID Value ID1 A-B-A-C-A ID2 A-B ID3 A-C-C Expected Output : ID
最后栈中的元素需要按匹配成功次数还原才是答案:例如: [s, c], [2, 1]。 答案应该是ssc。 classSolution:defremoveDuplicates(self,s:str,k:int)->str:num_st=[]cnt_st=[]foriinrange(len(s)):ifnotnum_stornum_st[-1]!=s[i]:num_st.append(s[i])cnt_st.append(1)else:cnt_st[-1]+=1...
