prefix / suffix [terminology]

Terminology¶

Usage¶

• Use for accumulations strictly before or after the current position.
• They communicate direction and excluded boundaries.
• Keep the full names because abbreviations such as pref and suff save little and are less balanced.
• Do not rename them to total; they may be multiplicative accumulators.

prefix = 1

for i in range(n):
    res[i] = prefix
    prefix *= nums[i]
