Compute the L2 norm of a vector

Easy

Problem Description

Given a list of numbers, compute its L2 (Euclidean) norm: sqrt(sum(x_i^2)).

Input: One line of space-separated numbers.

Output: The L2 norm (a single number). Round to 2 decimal places for comparison.

Example:

  • Input: 3 4
  • Output: 5.0 (sqrt(9+16) = 5)

Input & Output Format

INPUT:
Two lines. First line: space-separated numbers for vector a.
Second line: space-separated numbers for vector b.
OUTPUT:
A single number (the dot product).

Example

Input:
1 2 3
4 5 6
Output:
32
Explanation: 1×4 + 2×5 + 3×6 = 4 + 10 + 18 = 32
