number is palindrome or not code example

Example 1: check if palindrome

function isPalindrome(str) {
  str = str.toLowerCase();
  return str === str.split("").reverse().join("");
}

Example 2: Write a program to check whether inputted string is palindrome or not.

#include <stdio.h>
#include <string.h>
 
int main()
{
    char s[1000];  
    int i,n,c=0;
 
    printf("Enter  the string : ");
    gets(s);
    n=strlen(s);
 
    for(i=0;i<n/2;i++)  
    {
    	if(s[i]==s[n-i-1])
    	c++;
 
 	}
 	if(c==i)
 	    printf("string is palindrome");
    else
        printf("string is not palindrome");
 
 	 
     
    return 0;
}

Example 3: palindrome

function isPalindrome(text) {
  return [...text].reverse().join('') === text;
}

isPalindrome = text => {
	return [...text].reverse().join('') === text;
}

isPalindrome = text => [...text].reverse().join('') === text;

Example 4: palindrome

#include <stdio.h>
int main() {
    int n, reversedN = 0, remainder, originalN;
    printf("Enter an integer: ");
    scanf("%d", &n);
    originalN = n;

    // reversed integer is stored in reversedN
    while (n != 0) {
        remainder = n % 10;
        reversedN = reversedN * 10 + remainder;
        n /= 10;
    }

    // palindrome if orignalN and reversedN are equal
    if (originalN == reversedN)
        printf("%d is a palindrome.", originalN);
    else
        printf("%d is not a palindrome.", originalN);

    return 0;
}
