Question

Check whether a number is Adam number or not

(Adam number is a number whose square of the number and the square of the reversed number should be reverse to each other)

				
					Enter the number:
13
SQUARE OF 13 IS :169
REVERSE OF 13 IS :31
SQUARE OF REVERSE OF NUMBER(31) IS :961
REVERSE OF 961 IS :169
SQUARE OF NUMBER IS EQUAL TO REVERSE OF SQUARE OF REVERSED NUMBER THEREFORE,
13 IS AN ADAM NUMBER



Enter the number:
19
SQUARE OF 19 IS :361
REVERSE OF 19 IS :91
SQUARE OF REVERSE OF NUMBER(91) IS :8281
REVERSE OF 8281 IS :1828
SQUARE OF NUMBER IS NOT EQUAL TO REVERSE OF SQUARE OF REVERSED NUMBER THEREFORE,
19 IS NOT AN ADAM NUMBER
