Given a number N. The task is to create an alphabetical string in lower case from that number and tell whether the string is palindrome or not. a = 0, b = 1….. and so on.
For eg: If the number is 61 the substring “gb” will be printed till 7 (6+1) characters i.e. “gbgbgbg” and check if palindrome or not.
Note: No number will start with zero. Consider alphabets ‘ a to j ‘ only i.e. single digit numbers from 0 to 9.
Input: N = 61
Numbers 6, 1 represent letters ‘g’, ‘b’ respectively. So the substring is ‘gb’ and the sum is 7(6+1). Thus the alphabetical string formed is ‘gbgbgbg’, and is a palindrome.
Input: N = 1998
Numbers 1, 9, 8 represent letters ‘b’, ‘j’ and ‘i’ respectively. So the substring is ‘bjji’ and sum is 27(1+9+9+8). Thus the alphabetical string formed is bjjibjjibjjibjjibjjibjjibjj’, and is not a palindrome.
- Obtain the substring corresponding to given number N and maintain its digit’s sum.
- Append the substring till its length becomes equal to the sum of digits of N.
- Check if the string obtained is Palindrome or not.
- If it is a Palindrome, print YES.
- Else, print NO.
Below is the implementation of the above approach:
- Check if a string is palindrome in C using pointers
- C Program to Check if a Given String is Palindrome
- Check if a given string is a rotation of a palindrome
- Check if any anagram of a string is palindrome or not
- Given two strings check which string makes a palindrome first
- Recursive function to check if a string is palindrome
- Python program to check if a string is palindrome or not
- Check if there exists any sub-sequence in a string which is not palindrome
- Check if characters of a given string can be rearranged to form a palindrome
- Python program to check if given string is vowel Palindrome
- Check if a string can be rearranged to form special palindrome
- Check if the characters in a string form a Palindrome in O(1) extra space
- Create a new string by alternately combining the characters of two halves of the string in reverse
- Convert the string into palindrome string by changing only one character.
- Check if a number is Palindrome in PL/SQL
