Question 1:This is a dynamic programming problem, the state transition equation isDp[i] = dp[i-3] + dp[i-1], i>= 3 (iI'm just opening a DP array here. Resolves the problem. Initialized in the Init method.Also, given the convenience of testing, I used a recursive function, DFS (M,N,STR), to output all cases. See Code in detail: The function of a DFS function is to output all possible scenarios.For example: When I enter 5, the output:4All Programs:11111211121112At the same time I set the range of

Today there is a balance point, you say 3 find some time, different objects (the weight of the object is different than the other 111 light or heavy unknown).Solving:The 12 objects are numbered sequentially from 1-12.watermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqvd29vzhk4ote=/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/ Dissolve/70/gravity/southeast ">Copyright notice:

1, write script implementation, you can use Shell, Perl and so on. Locate 100 files starting with ABC under directory/tmp, and then save the first line of these files to the file new. 2, write script implementation, you can use Shell, Perl and so on. Save all the rows in file B, but none in file a , to file C and count the number of lines in C. Solution Ideas:1: Feel better with the shell, the code is as follows #!/bin/shfor filename in ' find/tmp-type f-name ' abc* ' |head-n ' d
