Hello @Amzad-Choudhary-353751958569219,

The formula you are using is wrong:
ans=ans+(last_dgtlast_dgt*last_dgt);

Reason:
You are adding the square of the digits irrespective of the number of digits in the number.
Solution:
Rather add the digit^(no. of digits in the number) i.e. the the digit raised to power the number of digits in the number.
Suggestion:
Refer to the examples given in the question.

Hope, this would help.
Give a like if you are satisfied.

Hello @Amzad-Choudhary-353751958569219,

  1. Your code will work only for armstrong number of 3 digits.

  2. Output format is incorrect.
    True should be true
    and False should be false.

Correct code:

Hope, this would help.
