第10个完美数: 2096128 很明显,120不是一个完美数,因此,可以确定Leetcode平台遗漏了这些cases,已经将此问题提交到Leetocode,如下所示: 05 正解 如果遍历所有的小于num的数,check是否为其因子,时间复杂度为o(n),在平台上提交会超时。 一种更好的解法,时间复杂度为O(sqrt(n)), 因为num的两个因子:num_i和...
Python Code:# Define a function named 'perfect_number' that checks if a number 'n' is a perfect number def perfect_number(n): # Initialize a variable 'sum' to store the sum of factors of 'n' sum = 0 # Iterate through numbers from 1 to 'n-1' using 'x' as the iterator for x...
这是一道leetcode题(No.507),我前段时间写过一个解,在leetcode平台上已通过: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 classSolution:defcheckPerfectNumber(self,num:int)->bool:sum=1tmp=numifnum==0or num==1:returnFalsewhilenum%2==0:num/=2sum+=num+tmp/numreturnsum==tmp 已知完美数...
We use an automated processes to find bugs. In the issue trackers for other decompilers, you will find a number of bugs we've found along the way. Very few to none of them are fixed in the other decompilers. The code in the git repository can be run from Python 2.4 to the latest...
This method involves iterating through numbers less than 20 and using a helper function to check if each number is prime. Example: Here is the complete Python code and an example. def is_prime(num): if num <= 1: return False for i in range(2, int(num**0.5) + 1): ...
