You are given an integer array \(A\) consisting of \(N\) elements. For each element, you are required to find the length of the valley that is defined as:
Let \(i\) be the current index and \(l\) and \(r\) be the leftmost and rightmost index satisfying this property \(a[l]>a[l+1].....>a[i-1]>a[i]<a[i+1]<... a[r-1]<a[r]\), then \((r-l+1)\) is the length of the valley. Also, assume that if \(A\) is \([7,2,1,5,7,9]\), then the answer is \([1,2,6,3,2,1]\).
Explanation
- A1 (7): The answer is 1 because there is no element to the left and in right 2 is smaller than 7.
- A2 (2): A1>A2, therefore, the answer is 2
- A3 (1): A1>A2>A3<A4<A5<A6, therefore, the answer is 6
- A4 (5): A4<A5<A6, therefore, the answer is 3
- A5 (7): A5<A6, therefore, the answer is 2
- A6 (9): 7 is smaller than 9 and there is no element to the right, therefore, the answer is 1
Input format
- The first line contains an integer \(T\) denoting the number of test cases.
- The first line of each test case contains an integer \(N\) denoting the number of elements in array \(A\).
- The second line of each test case contains \(N\) space-separated integers of array \(A\).
Output format
Print \(T\) lines. For each test case, print \(N\) space-separated integers denoting the length of the valley for each index.
Constraints
\(1 \leq T \leq 20000\)
\(1 \leq N \leq 500000\)
\(1 \leq A_i \leq 10^9\)
Sum of \(N\) over all test cases does not exceed 1000000
