Given a string containing digits from 2-9 inclusive, return all possible letter combinations that the number could represent.A mapping of digit to letters (just like on the telephone buttons) is given below. Note that 1 does not map to any letters.Example:Input: "23"
Output: ["ad", "ae", "af", "bd", "be", "bf", "cd", "ce", "cf"].
Note:Although the above answer is in lexicographical order, your ans...
如果你通过CSV Data Set Config或者_StringFromFile函数来参数化你的请求，需要特别注意当参数为纯数字时，jmeter会默认将其识别成int型数据，说明jmeter并不是默认以String类型对数据进行读取的:范围-2147483648到2147483647,如果超出这个范围（例如2147483648这个数字）：jmeter控制台则会抛出如下异常：jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval Parse error at line 14, column 181 : Error or n...
Palindrome NumberDetermine whether an integer is a palindrome. Do this without extra space.click to show spoilers.Some hints:
Could negative integers be palindromes? (ie, -1)If you are thinking of converting the integer to string, note the restriction of using extra space.You could also try reversing an integer. However, if you have solved the problem "Reverse Integer", you know that the reversed ...
el-input的type=“number” 隐藏上下增减标和禁止鼠标滚轮滚动
使用场景描述：
经常遇到需要对输入的数字进行限制，使用type=“number” 会出现：右侧滚轮会随着鼠标滚动上下滑动增减值（默认以1为跨步），现在需要去掉这个效果需要两个步骤：
第1步在样式中隐藏右测滚动（只是隐藏，滚动仍会出现数值的增减，此时需要做第2步）

这道题思路很简单，就是在一个loop下找最大的和第二大的数值。记住，python最小的数值是-sys.maxsize-1class Solution:def dominantIndex(self, nums: List[int]) -> int:ifnot nums or len(nums) == 1:return 0largest, sec_largest, idx = -sys.maxsize - 1, -sys.maxsize - 1, 0for i in range(len(nums)):if nums[i] >= largest: sec_largest = largestlargest = nums[i] idx = iif nums[i] > sec_largest and nums[i] < larg...

F(n) = a*F(n-1) + b*F(n-2);
S(n) = F1^k + F2^k +….+Fn^k;
求S(n) mod m;
解题思路：
1:首先一个难题就是怎么判断矩阵的维数（矩阵的维数是个变量）
解决方法：开一个比较大的数组，然后再用一个公有变量记一下就行了，具体详见代码；
2：k次方，找规律；
具体上代码吧：/*

Given an array containing n distinct numbers taken from 0,1, 2, ..., n, find the one that is missing from the array.
For example,
Given nums = [0, 1, 3] return 2.Note:

Given two strings representing two complex numbers.You need to return a string representing their multiplication. Note i2 = -1 according to the definition.Example 1:Input: "1+1i", "1+1i"
Output: "0+2i"
Explanation: (1 + i) * (1 + i) = 1 + i2 + 2 * i = 2i, and you need convert it to the form of 0+2i.
Example 2:Input: "1+-1i", "1+-1i"
Output: "0+-2i"
Explanation: (1 - i) * (1 - i) = 1 + i2 - 2 * i ...
