Kiyomaru has an array A of size n. He has 2 magical spells known as “Zakeru” and “Zakerga” which he can perform on that array.

Zakeru is a powerful spell which he formally represents as F.
F(i) : Applying this spell on an index i such that 0 <= i <= n-1 returns the smallest index j such that i < j <= n-1 and A[i] < A[j]. It returns -1 if there is no such index.

Zakerga is another powerful spell represented as G.
G(i) : Applying this spell on index i such that 0 <= i <= n-1 returns the smallest index j such that i < j <= n-1 and A[i] > A[j]. It returns -1 if there is no such index.

Now kiyomaru combines the power of these spells into one and names it “Zaker”.
This spell is equal to casting Zakeru first and Zakerga afterwards.

Formally he represents Zaker as Z.
Z(i) : G(F(i))

Now he is curious to know the values of those indices that he gets after performing Zaker spell on each index.
