Provide a correct Python 3 solution for this coding contest problem.
Given n numbers a0, a1, ..., an-1 and q.
I want you to perform appropriate processing for q queries.
The query has the following three types of operations.
* Shift the value
Given a pair of l and r. (l <r) Circular shift the value from al to ar.
0 1 2 3 4 5 6 7 8 9
Is given the query l = 2, r = 5.
The shifted number sequence is
0 1 5 2 3 4 6 7 8 9
Will be.
* Find the minimum value
Given a pair of l and r. (l ≤ r)
Find the smallest value from al to ar.
* Update value
Given a pair of pos and val. Update the value of apos to val.
Input
The input is given in the following format.
n q
a0
a1
..
..
..
an-1
x1 y1 z1
x2 y2 z2
..
..
..
xq yq zq
If xi = 0, it represents a shift query. At this time, let l = yi and r = zi.
If xi = 1, it represents a query for the minimum value. At this time, let l = yi and r = zi.
If xi = 2, it represents a query that updates the value. At this time, pos = yi, val = zi.
Input meets the following constraints
1 ≤ n, q ≤ 200,000
0 ≤ ai ≤ 10,000,000 For queries that update values, 0 ≤ val ≤ 10,000,000
Output
When xi = 1 is given as a query, output the value of the answer on one line.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Leo has developed a new programming language C+=. In C+=, integer variables can only be changed with a "+=" operation that adds the right-hand side value to the left-hand side variable. For example, performing "a += b" when a = 2, b = 3 changes the value of a to 5 (the value of b does not change).
In a prototype program Leo has two integer variables a and b, initialized with some positive values. He can perform any number of operations "a += b" or "b += a". Leo wants to test handling large integers, so he wants to make the value of either a or b strictly greater than a given value n. What is the smallest number of operations he has to perform?
Input
The first line contains a single integer T (1 ≤ T ≤ 100) — the number of test cases.
Each of the following T lines describes a single test case, and contains three integers a, b, n (1 ≤ a, b ≤ n ≤ 10^9) — initial values of a and b, and the value one of the variables has to exceed, respectively.
Output
For each test case print a single integer — the smallest number of operations needed. Separate answers with line breaks.
Example
Input
2
1 2 3
5 4 100
Output
2
7
Note
In the first case we cannot make a variable exceed 3 in one operation. One way of achieving this in two operations is to perform "b += a" twice.
