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. /*** 1 hop steps* Question: there are N levels in a step. If you can skip 1 level at a time, you can also skip 2 levels.* Calculate the total

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 case which gives the positive N (Output Specif

There are four threads of 1, 2, 3, 4.The function of thread 1 is output 1,The function of thread 2 is output 2, etc... There are now four file ABCD.The initial is empty.Now you want four files to appear in the following format:A:1 2 3 4 1 2 ....B:2 3 4
