I tried to solve USACO silver,I solved some problems in sorting and searching section,but I got stuck on binary search problems They are too complicated for me and I want to practice blindly for silver section and for increasing my cf rating Can you suggest something? Can you give some advices?
my advice is to practice and read solutions after 30 minutes to an hour of thinking if you get stuck, increasing the level slowly, and read articles online on what you are solving if you want extra knowledge.

If you get stuck on a problem, set it aside for a moment and come back to it later.
As a USACO Gold competitor, think of binary search as a series of 0s(invalid answers) followed by a series of 1s(valid answers). This advice gave me a lot of insight when learning binary search.
where did you practice? How can I find problems which challenging me?
Codeforces has tags :), I'd recommend that you start from 1100 and progress up by solving 3 in each level until you can't solve without editorial. Then, use the advice above "to practice and read solutions after 30 to an hour of thinking". Good luck!
I often just practice USACO problems and CSES problems.
uscao problems are too hard even if the tag is easy
Practice, practice, and more practice :D
Thanks
No prob! I wish you luck, last season, USACO Silver was very tough. :)
