Find the sum of all the four-digit palindromic numbers with The Geometer's Sketchpad program. When we will reverse its digit it will remain same number i. The sum is 9 + 9 = 18. For example, some palindrome numbers are 8, 121, 212, 12321, -454. Number Palindrome Check num=123; temp=num; sum_of_digits=0 revnum=0; while temp >0: revnum=revnum*10+temp%10; sum_of_digits=sum_of_digits+temp%10; temp=temp/10; print num,revnum,sum_of_digits if num==revnum: print ("The Number Entered is Palindrome") else: print ("The number is not palindrome"). Let’s say the number we want to check palindrome is 16461. 5 sum=sum+(rem*rem*rem) 7. In this procedure, reverse the digits of the original number and add the two numbers together. (2^3+1)/3, (2^31+1)/3, (2^13+1)/3, and (2^313+1)/3 are prime. A palindromic number is a number (in some base b) that is the same when written forwards or backwards. /*A number is called palindromic if its decimal representation is a palindrome. Help to her to write code. To understand below example, you have must knowledge of following C++ programming topics; For Loop in C++ and Reverse Number Program in C++. For example: 12121 is palindrome as it reads same forward or reversed. But what is a palindrome? A palindrome is a word, phrase, verse, or sentence that reads the same backward or forward. Number Palindrome Check num=123; temp=num; sum_of_digits=0 revnum=0; while temp >0: revnum=revnum*10+temp%10; sum_of_digits=sum_of_digits+temp%10; temp=temp/10; print num,revnum,sum_of_digits if num==revnum: print ("The Number Entered is Palindrome") else: print ("The number is not palindrome"). Recently Banks initiated the study of the additive properties of palindromes, proving that every natural number is the sum of at most 49 numbers whose decimal representation is a palindrome [8.
