Given an array A of size N, there are two types of queries on this array.

1. $q l r$: In this query you need to print the minimum in the sub-array $A[l : r]$.
2. $u x y$: In this query you need to update $A[x] = y$.

Input:
First line of the test case contains two integers, N and Q, size of array A and number of queries.
Second line contains N space separated integers, elements of A.
Next Q lines contain one of the two queries.

Output:
For each type 1 query, print the minimum element in the sub-array $A[l : r]$.

Contraints:
$1 \le N, Q, y \le 10^5$
$1 \le l, r, x \le N$
