Can you solve this real interview question? 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
Instructions In this kata, you must create a digital root function. A digital root is the recursive sum of all the digits in a number. Given n, take t

这一节,我们来看看回溯算法。 回溯算法理论基础 什么是回溯 在二叉树的路径问题里,其实我们已经接触到了回溯这种算法。 例如我们在查找二叉树所有路径的时候,查找完一个路径之后,还需要回退,接着找下一个路径。 回溯其实可以说是我们熟悉的DFS,本质上是一种暴力穷举算法,把所有的可能都列举出来,所以回溯并不高效。
trunc(): Trunc removes digits after decimal point. round(): Round given number to the closest integer. setprecision(): Setprecision when used along with ‘fixed’ provides precision to floating point numbers correct to decimal numbers mentioned in the brackets of the setprecison. double pi = 3.1...
What would you need to change to handle the target sum-of-digits being 10 or greater? Can you think of an approach that does not require storing all numbers? (think callbacks) About the code: helper is perhaps more involved than it needs to be. We can merge some conditions: private voi...
