We know that the smallest four digit number is 1000
But if we write this number in reverse order, it will become
0001 which is not same as 1000
The next four digit number is 1001 and if we write this number
in reverse order, we again get
1001
Hence the smallest four digit number which does not change when
written in reverse order is
1001
