m / n [terminology]

Terminology¶

Usage¶

• Use n for the size of a one-dimensional sequence.
• Use m and n for matrix dimensions:
  • m: number of rows
  • n: number of columns
• Do not use n as a generic element variable.
• Cache the size when it is used repeatedly or makes loop bounds clearer.

n = len(nums)

m, n = len(matrix), len(matrix[0])
