Given an array of n integers which may contain duplicate elements, index of an element of this array is given to us, We need to find the final position of this element ( for which the index is given) in the array after stable sort is applied on the array.
The first line of input contains an integer T denoting the number of test cases. Each test case contains two integers n and idx. Next line contains space separated n elements in the array a.
Print the index(0 based indexing) of the element after a stable sort operation.
