Palindrome Number
Palindrome Number
Palindrome Number Program in Java
A number is a palindrome if it reads the same reversed, like 121 or 1331.
Java Program
int num = 121, rev = 0, temp = num;
while (temp != 0) {
rev = rev * 10 + temp % 10;
temp /= 10;
}
if (num == rev) System.out.println(num + " is Palindrome");
else System.out.println(num + " is Not Palindrome");Output
121 is Palindrome
How it Works
- We reverse the number digit by digit using % and /.
- If the reversed number equals the original, it is a palindrome.
Summary
- A number is a palindrome if it reads the same reversed, like 121 or 1331.
Palindrome Number Program in Java
एक संख्या palindrome है अगर उलटी पढ़ने पर भी वैसी ही हो, जैसे 121 या 1331।
Java Program
int num = 121, rev = 0, temp = num;
while (temp != 0) {
rev = rev * 10 + temp % 10;
temp /= 10;
}
if (num == rev) System.out.println(num + " is Palindrome");
else System.out.println(num + " is Not Palindrome");Output
121 is Palindrome
कैसे काम करता है
- हम संख्या को % और / से digit-by-digit उलटते हैं।
- उलटी संख्या original के बराबर हो तो palindrome है।
सारांश
- एक संख्या palindrome है अगर उलटी पढ़ने पर भी वैसी ही हो, जैसे 121 या 1331।
