At the children's day, the child came to Picks's house, and messed his house up. Picks was angry at him. A lot of important things were lost, in particular the favorite sequence of Picks.
Fortunately, Picks remembers how to repair the sequence. Initially he should create an integer array a[1],a[2],...,a[n]. Then he should perform a sequence of m operations. An operation can be one of the following:
  1. Print operation l,r. Picks should write down the value of .
  2. Modulo operation l,r,x. Picks should perform assignment a[i]=a[i]modx for each i (lir).
  3. Set operation k,x. Picks should set the value of a[k] to x (in other words perform an assignment a[k]=x).
Can you help Picks to perform the whole sequence of operations?
Input
The first line of input contains two integer: n,m (1≤n,m≤105). The second line contains n integers, separated by space: a[1],a[2],...,a[n](1≤a[i]≤109) − initial value of array elements.
Each of the next m lines begins with a number type .
  • If type=1, there will be two integers more in the line: l,r(1≤lrn), which correspond the operation 1.
  • If type=2, there will be three integers more in the line: l,r,x(1≤lrn;1≤x≤109), which correspond the operation 2.
  • If type=3, there will be two integers more in the line: k,x(1≤kn;1≤x≤109), which correspond the operation 3.
Output
For each operation 1, please print a line containing the answer. Notice that the answer may exceed the 32-bit integer.

Note
Consider the first testcase:
  • At first, a={1,2,3,4,5}.
  • After operation 1, a={1,2,3,0,1}.
  • After operation 2, a={1,2,5,0,1}.
  • At operation 3, 2+5+0+1=8.
  • After operation 4, a={1,2,2,0,1}.
  • At operation 5, 1+2+2=5.
