1837. Sum of Digits in Base K

Given an integer n (in base 10) and a base k, return the sum of the digits of n after converting n from base 10 to base k.

After converting, each digit should be interpreted as a base 10 number, and the sum should be returned in base 10.

Example 1:

Input: n = 34, k = 6
Output: 9
Explanation: 34 (base 10) expressed in base 6 is 54. 5 + 4 = 9.

Example 2:

Input: n = 10, k = 10
Output: 1
Explanation: n is already in base 10. 1 + 0 = 1.

def sumBase(self, n: int, k: int) -> int:
	def converttobasek(n, base):
		res = ''
		while n >= base: 
			add = n % base
			res = str(add) + res
			n = n // base
		res = str(n) + res
		return int(res)
	num = str(converttobasek(n,k))
	sum = 0
	for i in num:
		sum += int(i)
	return sum
