Python PyTorch ceil() and floor() methods, Precision of floating point numbers in C++ (floor(), ceil(), trunc(), round() and setprecision()). Find the floor and ceiling of 'X' in 'A[0..N-1]'. For Example:Input: N = 5, arr[] = {2, 4, 1, 3, 5}Output: 3Explanation: The sequence 2, 4, 1, 3, 5 has three inversions (2, 1), (4, 1), (4, 3). For an array, inversion count indicates how far (or close) the array is from being sorted. For example.
