The java implementation for 2224D solution 2 got TLE with Fenwick tree, but it passed with merge sort. Wondering why...
The solution for Problem $$$\textbf{Div2}$$$ $$$C$$$ is not clear!!
It may be more intuitive to apply the greedy algorithm to verify whether the value of the number of left parentheses minus the number of right parentheses in the two strings is valid.373672904.Hope it will help.
We are changing a new version of it. Hope it will help.
I created video editorial for D. Zhily and Barknights
