editorial for BINSTR

When will the editorial for binstr from november challenge be uploaded? there is an editorial for all other questions except this one


At this moment itself, I am writing the editorial for BINSTR, hoping to complete it by tonight.

Meanwhile, The brief idea is to create another array B which contains indices of strings in sorted order of string values and using persistent segment tree to check, if a range [l,r] in the original array contains any value in range [ll,rr] in B array. Two cases, when range [l,r] contains any string greater in length than query string and otherwise are to be handled separately.
