in this blog -searching for k-th zero, what does it mean?

is this the k-th zero is from the array.begin() to array.end()?

or, it is from the range from L to R, which will be given in the query? Thanks in advance.

First one.

The second one is the same tho. You just need (k + cnt_zero(0, L — 1))th zero
