Shell script to check if a string is a palindrome?

Answer 1

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"

Answer 2

public boolean palindrome(String string)
{
boolean isPalindrome = true;
char[] Character = new char[string.length()]
character[] = string.toCharArray();
for(int i = 0;i < string.length(); i++)
{
if(character[i] != character[string.length()-i])
isPalindrome = false;

}

return isPalindrome;

}
