Question

What is the Palindrome number?
Which is the smallest palindrome no.? ​

Answer 1

palindromic number is a number that remains the same when its digits are reversed. In other words, it has reflectional symmetry across a vertical axis. The term palindromic is derived from palindrome, which refers to a word whose spelling is unchanged when its letters are reversed

Smallest N-digit Palindromic Number: On observing carefully, you will observe that for N = 1, the smallest palindromic number will be 0. And for any other value of N, the smallest palindrome will have the first and last digits as 1 and all of the digits in between as 0. Case 1 : If N = 1 then answer will be 0.

Answer 2

A number maintains the same value even though the digits are reversed is called palindrome number.

Step-by-step explanation:

1. A number maintains the same value even though the digits are reversed is called palindrome number.
2. The smallest palindrome number is zero.
3. For example 0 has only 1 digit in it. If we reverse it same 0 will come.  
4. The smallest double digit palindrome number is 11.
5. The smallest palindrome number can be obtained using the formula $10^{N-1}+1$ where N denote the number of digits but N is not equal to 1.
