Slice Fields Out of a Fixed-Width Record Tuple

Easy ⏱ 8 min 74% acceptance ★★★★☆ 4.4

Given a record tuple row = (id, name, department, salary, hire_year), implement contact_fields(row) returning a new tuple with only name and department (indexes 1 and 2), using tuple slicing. Then implement trailing_fields(row) returning the last two elements (salary, hire_year), also via slicing.

Examples

Example 1

Input

contact_fields((7, 'Neha', 'Engineering', 120000, 2021))

Output

('Neha', 'Engineering')

Explanation

row[1:3] slices out indexes 1 and 2.

Example 2

Input

trailing_fields((7, 'Neha', 'Engineering', 120000, 2021))

Output

(120000, 2021)

Explanation

row[-2:] grabs the final two elements.

Constraints

row always has exactly 5 elements in the stated order.
