https://leetcode.com/problems/palindrome-number/ Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward.정수형 숫자가 회문인지 아닌지 판단하시오. 앞에서부터 읽어도 뒤에서부터 읽어도 같은 경우 회문인 숫자입니다. Example 1:Input: 121Output: trueExample 2: Example 2:Input: -121Output: falseExplanation: From left to right, it reads -121. From right to left, it becomes 121-. Therefore ..

https://leetcode.com/problems/reverse-integer/ Given a 32-bit signed integer, reverse digits of an integer. 32비트의 부호있는 정수가 있다, 정수의 숫자를 반전시켜라. Example 1:Input: 123Output: 321 Example 2:Input: -123Output: -321 Example 3:Input: 120Output: 21 Note: Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231, 231 − 1]. For the purpose of thi..

https://leetcode.com/problems/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 contain a single digit. Add the two numbers and return it as a linked list. You may assume the two numbers do not contain any leading zero, except the number 0 itself. Example:Input: (2 -> 4 -> 3) + (5 -> 6 -..

https://leetcode.com/problems/two-sum/ Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have exactly one solution, and you may not use the same element twice. Example :Given nums = [2, 7, 11, 15], target = 9, Because nums[0] + nums[1] = 2 + 7 = 9,return [0, 1]. 주어진 정수배열에서 더하여 특정값이 되는 두 숫자의 인덱스를 반환하라.각 입..
