Leetcode Problem (Easy) IsPalindrome

By

 Given an integer x, return true if x is a 

, and false otherwise.

 

Example 1:

Input: x = 121
Output: true
Explanation: 121 reads as 121 from left to right and from right to left.

Example 2:

Input: x = -121
Output: false
Explanation: From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not a palindrome.

Example 3:

Input: x = 10
Output: false
Explanation: Reads 01 from right to left. Therefore it is not a palindrome.

 

Constraints:

  • -231 <= x <= 231 - 1

Solution:-
class Solution {
    public boolean isPalindrome(int x) {
       
    int temp = x;
      int sum = 0;
      int r  = 0 ;
      if(x>0){
          while(x>0){
              r = x % 10;
              sum = (sum*10) + r;
              x = x /10;
          }
      }
        return sum == temp;
    }
}

Leetcode Problem(Easy) Roman to Integer

By
  Roman numerals are represented by seven different symbols:  I ,   V ,   X ,   L ,   C ,   D   and   M . Symbol Value I 1 V 5 X 10 L 50 C 100 D 500 M 1000 For example,  2  is written as  II  in Roman numeral, just two ones added together.  12  is written as  XII , which is simply  X + II . The number  27  is written as  XXVII , which is  XX + V + II . Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not  IIII . Instead, the number four is written as  IV . Because the one is before the five we subtract it making four. The same principle applies to the number nine, which is written as  IX . There are six instances where subtraction is used: I  can be placed before  V  (5) and  X  (10) to make 4 an...
