上题目:leetcode-cn.com/problem显然,字符串比数字更好处理,这道题显然是需要动态规划【递归】的 主要是对含有0的字符的处理,披露06 常理来说可以分为 0/6或者06,但是0/6识别为a/g,06不能识别 所以需要对0单独处理 class Solution: def translateNum(self, num: int) -> int: def
classSolution {public:intremove(vector<int> nums,intval) {intk =0;//定义个索引k 初值为数组首位//遍历数组 使[0 k)区间为非val元素for(inti =0; i < nums.size(); i++)if(nums[i] !=val) nums[k++] =nums[i];returnk;//返回索引值} }; 思路2: 代码参考:https://github.com/liuyubo...
16 classSolution(object): defremoveElement(self, nums, val): """ :type nums: List[int] :type val: int :rtype: int """ i=0 n=len(nums) j=0 whilei<n: ifnums[i]!=val: nums[j]=nums[i] j+=1 i+=1 returnj
classSolution{public:stringcompressString(stringS){int i=0,j=0;int n=S.size();string tmp;// 「外层循环」i 指向每个首次出现的字符while(i<n){// 「内层循环」j 向前遍历,直到字符串末尾或找到与 s[i] 不同的字符时跳出while(j<n&&S[i]==S[j])j++;// 压缩字符串,添加至 tmptmp+=S[i]...
