Task 1 — Maximum Value per Group

Objective

Create a function that processes a two-dimensional integer collection and finds the maximum value from each inner group.

The function must return one maximum value for every group in the input.

Input

The input is:

[][]int

Example:

data := [][]int{
    {32, 12, 24, 20},
    {18, 40, 22, 30},
    {21, 31, 42, 35},
}

The input contains three groups.

Result Type

The function must return:

[]int

Each position in the result represents the maximum value found in the corresponding input group.

Requirements

Process every inner slice independently.

For each group:

1. inspect all values in the group
2. determine the maximum value
3. append that value to the result

The order of the result must correspond to the order of the input groups.

Example

Given:

data := [][]int{
    {32, 12, 24, 20},
    {18, 40, 22, 30},
    {21, 31, 42, 35},
}

the maximum values are:

Group 1 -> 32
Group 2 -> 40
Group 3 -> 42

Expected Result

[]int{32, 40, 42}

Implementation Notes

The implementation should work with other valid two-dimensional integer collections and should not depend on the example values.

The original task does not specify a function name.

Consider how the implementation should handle an empty inner group if support for such input is required.

The original specification does not define behavior for empty groups, so that behavior should be explicitly decided by the implementation rather than silently assumed.
