Determine whether an integer is a palindrome. Do this without extra space. Some hints: Could negative integers be palindromes? (ie, -1) If you are thinking of converting the integer to string, note the restriction of using extra space. You could also try reversing an integer. However, if ...

1) While loop is entry checking loop, it checks the condition then only executes the code. 2) Check the condition at outer while, for, given i value, if it is true then j=1, 1st inner loop prints space until the condition j++<=n-i is false. 3) j value initialized to 1 and 2n...
