Implement dot product of two vectors
EasyProblem Description
Given two lists of numbers (vectors), compute their dot product.
The dot product of vectors a and b is: sum(a[i] * b[i]) for all i.
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 3and4 5 6 - Output:
32(14 + 25 + 3*6 = 4+10+18 = 32)
Input & Output Format
INPUT:
Two lines. First line: space-separated numbers for vector a.
Second line: space-separated numbers for vector b.
Second line: space-separated numbers for vector b.
OUTPUT:
A single number (the dot product).
Example
Input:
1 2 3
4 5 6
4 5 6
Output:
32
Explanation: 1×4 + 2×5 + 3×6 = 4 + 10 + 18 = 32
