Algorithm

·                     Start

·                     Declare string[25], revstring[25] = {'\0'} as character

·                     Declare i, length=0; flag=0 as integer

·                     Write("the string")

·                     gets(string)

·                     for(i=0;string[i]!='\0';i++)

·                     length++

·                     for(i=length-1;i>=0;i--)

·                     revstring[length-1] = string[i]

·                     if(revstring[i]==string[i])

·                     flag=1

·                     else

·                     flag=0

·                     if(flag==1)

·                     Read(“It is not a palindrome”)

·                     else

·                     Read("It is a palindrome")

·                     Stop
