Given an Array \'A\' of size \'N\', find the number of Subarrays which have median equal to \'M\'. Median of the array is defined as : \n*  If \'N\' is odd then the median is middle of the sorted array\n*  If \'N\' is even then the median is left of two middle values of the sorted  array.\n\n```\nInput - [2, 1, 3, 5, 4] , N = 5 , M = 2\nOutput - 3\nExplanation : The subarrays are [2], [2,1,3] and [2,1,3,5] hence count is 3.\n```\nNote - Count of \'M\' can be more than 1 in the array.\nCan anyone solve it in O(n)?
