Prepare the string for processing: Remove all punctuation from the string (e.g., commas, hyphens, whitespace, etc). Convert to the same case (e.g., lower-case). Instantiate two pointers, one pointing at the first character, the other pointing at the last character. Process: If the two pointers are pointing at the same position or have crossed each other, the string is a palindrome. Otherwise, compare the characters being pointed at. If they are not equal, the string is not a palindrome. Otherwise, move both pointers one position towards the middle of the string and repeat the process.

You can do this: <?php if ( $word === strrev( $word ) ) { echo "The word is a palindrome"; } else { echo "The word is not a palindrome"; }

To check if a string is a palindrome, point to each end of the string and work inwards towards the middle. If the characters pointed at differ, the string is not a palindrome. When the pointers meet or cross each other, the string is a palindrome. Note that the string cannot contain whitespace or punctuation and comparisons must not be case-sensitive.
It is a simple program. i think u may understand it :#include#include#includevoid main(){char s[10]=answers.com;char x[10];int a;clrscr();strcpy(x,s);strrev(s);a=strcmp(s,x);if(a==0){printf("the entered string is palindrome");}else{printf("the entered string is not palindrome");}output:given string is not palindrome
If you want to check whether a string is a palindrome, you can reverse the string (for example, the Java class StringBuffer has a reverse() method), and then compare whether the two strings - the original string and the reverted string - are equal. Alternately, you could write a loop that checks whether the first character of the string is equal to the last one, the second is equal to the second-last one, etc.; that is, you have a counter variable (in a "for" loop) that goes from zero to length - 1 (call it "i"), and compare character #i with character #(length-i-1) inside the loop.
len=0 i=1 echo -n "Enter a String: " read str len=`echo $str | wc -c` len=`expr $len - 1` halfLen=`expr $len / 2` while [ $i -le $halfLen ] do c1=`echo $str|cut -c$i` c2=`echo $str|cut -c$len` if [ $c1 != $c2 ] ; then echo "string is not palindrome" exit fi i=`expr $i + 1` len=`expr $len - 1` done echo "String is Palindrome"
You could use a function like this:function isPalindrome($string) {$string = strtolower($string);return (strrev($string) == $string) ? true : false;}and then to check a palindrome call an if statement like so:if(isPalindrome($test)) {echo $test.' is a palindrome';}else {echo $test.' is not a palindrome';}
