For example, the method for determining whether a number can be divisible by 7 is as follows: for example, if 344617 can be divisible by 7, 617-344 = 273,273 can be divisible by 7, so 344617 can be divisible by 7. For example, if 4241468 can be divisible by 7, 468-241 + 4 = 231 can be divisible by 7. So how can we prove this method when 4241468 can be divisible by 7? It is best to answer in Chinese. It is easy to use.
The technique is very simple. You only need 1001 = 7*11*13. Please take a loo

Flood problem ...The topic asks you to ask to see the number of lanterns, we can divide into 3 parts
Total number of Lanterns —————— 1
In l The number of lanterns on the left (excluding ll
Number of lanterns on the left of R (including RRR) —————— 3
We know that by the top 2-3 is the number of lanterns blocked by another trainSo 1-2+3 is the answer;Code:#include #include#include#include#defineRii Register int i#defineRij Register Int Jusing namespacestd;intt,len,l,r,v;voidsolve (
