Question: enter a string that represents an integer, convert it to an integer, and output it. For example, if the input string is "345", an integer of 345 is output. The question is simple, but it involves many problems, such as illegal input,

Input a positive integer N and return a minimum positive integer m (M is at least two digits), so that the product of M is equal to N, for example, input 36, output 49, input 100, output 455, if a certain N does not have such M, return-1. Package

Evaluate the number of 1 in the binary of an integer. Question: enter an integer to calculate the number of 1 in the Binary Expression of this integer. For example, input 10. Because the binary value is 1010 and there are two 1 s, Output 2. Analysis:
