Implement Softmax Function

MediumPython

Problem

Implement the softmax function based on the provided mathematical formula.

Given a non-empty list of real-valued logits, return a list of probabilities in the same order. Use a numerically stable implementation that avoids overflow for large logits. The output probabilities should sum to approximately 1, within normal floating-point tolerance.

Function signature: def softmax(logits): Input is list[float]; output is list[float].

Constraints

  • 1 <= len(logits) <= 1000
  • Each element of logits is a finite real number
  • Return values in the same order as the input
  • Results are evaluated with floating-point tolerance

Function Signature

def softmax(logits):
