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/E 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).
