Jul 19, 2020 · Those numbers, when the 1 has found, they will be a happy number. Suppose the number is 19, the output will be true as the number is a happy number. As we can see from 19, we will get. 12 + 92 = 82. 82 + 22 = 68. 62 + 82 = 100. 12 + 02 + 02 = 1. Here is my code: s = list(str(n))
Jun 30, 2022 · Wikipedia says following: In number theory, a happy number is a number which reaches 1 when replaced by the sum of the square of each digit. For example 82 is a happy number. (8² + 2² = 68 -> 6² + 8² = 100 -> 1² + 0² + 0² = 1). If a number is no happy number it convergates against 4. – Eminos. Jun 30, 2022 at 16:45.
1-The result is exactly 1. 2-You find your result in the list of already checked. Given this, here's how to fix your code, but I recommend you to try before checking the solution: def isHappy(self, n): checked = [] nums = str(n) while nums != '1' and not (nums in checked): checked.append(nums) result = 0.
Sep 5, 2020 · A happy number is a number defined by the following process: Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the number equals 1 (where it will stay), or it loops endlessly in a cycle which does not include 1.
Jan 25, 2018 · 1. If your main problem is that you want to have all your happy numbers in a list, you can easily address this by defining a list outside the recursion loop. def happynumber(num, counter): N = adder(num) if N == 1: happyhappy.append(number) #new happy number into list.
This is how I did , even though it is a bit messy. #Python program to check if a number is a happy number #Creating an user defined function which returns True if the number is happy else False def happy(num) : #Creating a copy of the number in a string and a iterating point copy = str(num) square = num #Proceeding with while loop due to unknown iterations while True : #inifinte loop square = sum(int(j) ** 2 for j in list(str(square))) #Sum of the number's digit squares if square == 1: test ...
May 3, 2017 · So my code should take the digits of a 2 digit number for example (22) and square the individual digits so to [4, 4]. Then add these so 8. Then repeat this till the sum = 1 or repeat endlessly if it

2. You can use % operator to check divisiblity of a given number. The code to check whether given no. is divisible by 3 or 5 when no. less than 1000 is given below: n=0. while n<1000: if n%3==0 or n%5==0: print n,'is multiple of 3 or 5'. n=n+1. edited Jan 12, 2016 at 19:19.
Jan 9, 2017 · But, if we find a happy number, then all the numbers we checked in the process of determing that it is happy, are themselves happy. Ditto for unhappy numbers. So if we add some caching, using dangerous default values that carry through to subsequent calls:
