2D Array Memory Layout

2D Array Memory Layout

MediumPython

Problem

How is a 2D array stored in memory? Implement a function that calculates the linear memory offset of an element in either row-major or column-major storage. The function receives the array dimensions, element coordinates, and storage order, then returns the zero-based offset in the contiguous memory block.

Constraints

  • 1 <= rows, cols <= 10000
  • 0 <= row < rows
  • 0 <= col < cols
  • order is either "row-major" or "column-major"
  • The array is stored contiguously without padding

Function Signature

def memory_offset(rows, cols, row, col, order):
