standard inputoutput

standard outputFafa has an array *A* of *n* positive integers, the function *f*(*A*) is defined as . He wants to do *q* queries of two types:

- 1
*l**r**x*— find the maximum possible value of*f*(*A*), if*x*is to be added to one element in the range [*l*,*r*]. You can choose to which element to add*x*. - 2
*l**r**x*— increase all the elements in the range [*l*,*r*] by value*x*.

Note that queries of type 1 don't affect the array elements.

Input

The first line contains one integer *n* (3 ≤ *n* ≤ 10^{5}) — the length of the array.

The second line contains *n* positive integers *a*_{1}, *a*_{2}, ..., *a*_{n} (0 < *a*_{i} ≤ 10^{9}) — the array elements.

The third line contains an integer *q* (1 ≤ *q* ≤ 10^{5}) — the number of queries.

Then *q* lines follow, line *i* describes the *i*-th query and contains four integers *t*_{i} *l*_{i} *r*_{i} *x*_{i} .

It is guaranteed that at least one of the queries is of type 1.

Output

For each query of type 1, print the answer to the query.
