1	Two Sum	Given an array of integers `nums` and an integer `target`, return indices of the two numbers such that they add up to `target`. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order.

2	Add Two Numbers	You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each of their nodes contains a single digit. Add the two numbers and return the sum as a linked list.

4	Median of Two Sorted Arrays	Given two sorted arrays `nums1` and `nums2` of size `m` and `n` respectively, return the median of the two sorted arrays. Example 1: Input: nums1 = [1,3], nums2 = [2] Output: 2.00000 Explanation: merged array = [1,2,3] and median is 2.

7	Reverse Integer	Given a signed 32-bit integer `x`, return `x` with its digits reversed. If reversing `x` causes the value to go outside the signed 32-bit integer range `[-231, 231 - 1]`, then return `0`. Assume the environment does not allow you to store 64-bit integers (signed or unsigned).

8	String to Integer (atoi)	Implement the `myAtoi(string s)` function, which converts a string to a 32-bit signed integer (similar to C/C++'s `atoi` function). The algorithm for `myAtoi(string s)` is as follows: Read in and ignore any leading whitespace. Check if the next character (if not already at the end of the string) i…	Medium	/articles/string-to-integer	15.7	56	https://leetcode.com/problems/string-to-integer-atoi	999	716.1K	4.6M	Facebook,Amazon,Microsoft,Google,Goldman Sachs,Apple,Adobe,Bloomberg,Intel	Math,String	189	479	28	1	[Reverse Integer, /problems/reverse-integer/, Easy], [Valid Number, /problems/valid-number/, Hard]
9	Palindrome Number	Given an integer `x`, return `true` if `x` is palindrome integer. An integer is a palindrome when it reads the same backward as forward. For example, `121` is palindrome while `123` is not. Example 1: Input: x = 121 Output: true Example 2: Input: x = -121 Output: false Explanation: From left to …	Easy	/articles/palindrome-number	50	58.2	https://leetcode.com/problems/palindrome-number	999	1.2M	2.4M	Microsoft,Adobe,Bloomberg,Facebook,Google,Yahoo	Math	3199	1724	65	1	[Palindrome Linked List, /problems/palindrome-linked-list/, Easy]
10	Regular Expression Matching	Given an input string (`s`) and a pattern (`p`), implement regular expression matching with support for `'.'` and `''` where:` ` `'.'` Matches any single character. `''` Matches zero or more of the preceding element. The matching should cover the entire input string (not partial).
