Hi codeforces↵
↵
In some recently contest. I have found many problem with "constructive" tag.↵
In this such problem, we solve it by the way like : "If you construct a algorithm like ... you will reach the result. We↵
can prove that ..."↵
Example : E and C in Global round 15 : ↵

https://codeforces.com/contest/1552/problem/C↵
↵
Some time I feel it's too difficult to solve constructive problem. So I want to ask you how did you figure out a solution↵
for such that problem ?↵
↵
btw// I have learnt cp for 3 years, yah, not practive so much on codeforces but many on another platform.↵
Recently, I dicide to practice on cf more to reach at least CM on it. But, I feel it still impossible for me. But↵
I will never give up (booyah!). Uhm, if you have any experience, pls share to me, I will damn grateful for that↵
↵
Thanks for reading! (and sorry because my English).
