Some small algorithms are of the Java version, and a large number of questions on the network are aimed at C ++. Therefore, Java implementation is rare, but they are the basis of the test,
The implementation is the same. You can broaden your thinking and be helpful.

The task is simple:given any positive an integer N, you're supposed to count the total number of 1 's in the decimal form of The integers from 1 to N. For example, given N being, there is five 1 ' in 1, ten, one, and 12.Input Specification:Each input file contains one test c
Recently find an internship, in doing test assignment encountered such a problem, on the way to record:Said, there are 1 to 100 a total of 100 numbers, put into a circle. Starting from 1, every 1, 2, 3, 4 ... The number takes a number, keeps looping, and finally leaves a few
Question: Please 1 ~ The number of 1 in the integer n.
The general practice is to first write a sub-function with the right shift of 1, calculate the number of 1 in each number, and the
Number of occurrences of 1 in positive numbers from 1 to n
Topic:
Enter an integer n to find the number of occurrences of 1 in the decimal representation of the n integers from 1 to n.
For example, input 12, from

Problem DescriptionThe greatest common divisor GCD (a, B) of two positive integers a and B, sometimes written (a, B), is the largest divisor common to a and B, For example, (1, 2) = 1, (12, 18) = 6.(A, B) can be easily found by the Euclidean algorithm. Now Carp is conside
Given a function that randomly generates integers 1 through n, a function (M > N) that can randomly generate integers 1 to M is written.
Set n = 5, M = 7The key is to have the same probability of generating 1 to 7 of the number. Call N-time given function, generate n 1 to 5,

Recently had the honor to get a small interview question, studied the research, then shares out, hoped can be helpful to everybody's code cause.
The interview question is: Get 1-1000 of all occurrences of 1, and calculate the number of 1
Solution:
Copy Code code as follows:
Enumeration method can only be
Enumeration 1 -- calculate the maximum prime number less than n, enumeration 1 -- prime numberEnumeration 1 -- calculate the maximum prime number less than n
