Task 1: "Number Combinations
2+
3+
You are given two integers $m and $n. Write a script print all possible
4+
combinations of $n numbers from the list 1 2 3 ... $m.
5+
6+
Every combination should be sorted i.e. [2,3] is a valid combination but
7+
[3,2] is not.
8+
9+
Example:
10+
11+
Input: $m = 5, $n = 2
12+
13+
Output: [ [1,2], [1,3], [1,4], [1,5], [2,3], [2,4], [2,5], [3,4], [3,5], [4,5] ]
14+
"
15+
16+
My notes: generally I hate permutation questions, but this looks ok.
17+
18+
19+
Task 2: "Letter Phone
20+
21+
You are given a digit string $S. Write a script to print all possible letter combinations that the given digit string could represent.
22+
23+
(1 represents _ or @,
24+
2 A,B or C,
25+
3 D,E or F,
26+
4 G, H or I,
27+
5 J, K or L,
28+
6 M, M or O,
29+
7 P, Q, R or S,
30+
8 T, U or V,
31+
9 W, X, Y or Z
32+
letters from a phone panel)
33+
34+
Example:
35+
36+
Input: $S = '35'
37+
38+
Output: ["dj", "dk", "dl", "ej", "ek", "el", "fj", "fk", "fl"].
39+
40+
My notes: sounds pretty easy. Lookup the set of possibilities for each
41+
letter, then cross-product them.

# Task #1
2+
3+
Write a script to display months from the year 1900 to 2019 where you
4+
find 5 weekends i.e. 5 Friday, 5 Saturday and 5 Sunday.
5+
6+
## Solution
7+
8+
Months that contain five full weekends have 31 days and start on a Friday. Use `cal` to display March 2019 as an example.
9+
10+
```
11+
#$ cal -h -m 3 2019 # cal is a UNIX utility
12+
March 2019

19+

20+
```
21+
22+
The solution runs `cal` and displays months that match this unique
23+
layout.
24+
25+
# Task #2
26+
27+
Write a script that can wrap the given paragraph at a specified column
28+
using the greedy algorithm.
29+
30+
A simple way to do word wrapping is to use a greedy algorithm that
31+
puts as many words on a line as possible, then moving on to the next
32+
line to do the same until there are no more words left to place. This
33+
method is used by many modern word processors, such as OpenOffice.org
34+
Writer and Microsoft Word[citation needed]. This algorithm always uses
35+
the minimum possible number of lines but may lead to lines of widely
36+
varying lengths. The following pseudocode implements this algorithm:
37+
38+
```
39+
SpaceLeft := LineWidth
40+
for each Word in Text
41+
if (Width(Word) + SpaceWidth) > SpaceLeft
42+
insert line break before Word in Text
43+
SpaceLeft := LineWidth - Width(Word)
44+
else
45+
SpaceLeft := SpaceLeft - (Width(Word) + SpaceWidth)
46+
```
47+
48+
Where LineWidth is the width of a line, SpaceLeft is the remaining
49+
width of space on the line to fill, SpaceWidth is the width of a
50+
single space character, Text is the input text to iterate over and
51+
Word is a word in this text.
52+
53+
## Solution
54+
55+
The solution follows the recommended pseudocode. Minor improvements
56+
avoid trailing whitespace.
57+
58+
The script uses `Text::ParseWords::shellwords` from the standard
59+
library to extract chunks of words from `<STDIN>`.
