Well, I will not waste your time and go straight to the problem.

You are given an array A of numbers. And some queries. Each query consists of two ranges. You need to find out if those two ranges are similar or not. You are given a function to figure out if two ranges are same or not.

function IsSame(x1, y1, x2, y2)
Array1 = []
Array2 = []

For i = x1 to y1
Array1.push(A[i])
end For

For i = x2 to y2
Array2.push(A[i])
end For

NewArray1 = sort the elements inside Array1
NewArray2 = sort the elements inside Array2

return (NewArray1 equals NewArray2)
end function


## Input

The first line contains two integer N - number of elements in the array and Q - number of queries.
Next line contains N integers denoting the ith element of the array A.

Next there are Q queries with four integers which is described above.

• 1 ≤ N, Q ≤ 105
• 1 ≤ A[i] ≤ 105
• 1 ≤ x1, y1, x2, y2 ≤ N

## Output

For each query, use the function given above and if the function returns true value print "Yes" otherwise print "No" without quote .
