Medium ⏱ 12 min 47% acceptance ★★★★☆ 4.4

Sensor readings need to be compared pairwise. Write adjacent_pairs(readings) returning a list of (readings[i], readings[i+1]) tuples for every consecutive pair, using a comprehension over indices.

Examples

Example 1

Input

adjacent_pairs([3, 7, 1])

Output

[(3, 7), (7, 1)]

Explanation

Two overlapping windows of size 2.

Constraints

A list with fewer than 2 items yields [].
Use a comprehension.
