I am learning about Segment tree topic.

Let’s say you are given an array `ar`

whose size is `n`

and you build a segment tree for range minimum query. The segment tree size would be less than `4n`

.

for eg:

`given array : 1 23 4 51 6 7 with size of n=6`

in the given array, element `51`

is present at position `4`

(1-based indexing).

Now after building segment tree (which is stored in array of 1-based indexing), how can I get the index of element `51`

from the segment tree? At what index would it be stored in the segment tree?
