Task 1: "Strobogrammatic Number
2+
3+
A strobogrammatic number is a number that looks the same when looked at
4+
upside down.
5+
6+
You are given two positive numbers $A and $B such that 1 <= $A <= $B <= 10^15.
7+
8+
Write a script to print all strobogrammatic numbers between the given
9+
two numbers.
10+
11+
Example
12+
13+
Input: $A = 50, $B = 100
14+
Output: 69, 88, 96
15+
"
16+
17+
My notes: ok. Wikipedia suggests 0, 1, 6, 8 and 9 are only digits to consider,
18+
0, 1 and 8 are their own inverses, and 6 and 9 form the only inverse pair
19+
(unless you include 2 and 5 like on an 8-segment lcd display).
20+
21+
22+
Task 2: "0/1 String
23+
24+
A 0/1 string is a string in which every character is either 0 or 1.
25+
26+
Write a script to perform switch and reverse to generate S30 as described below:
27+
28+
switch:
29+
30+
Every 0 becomes 1 and every 1 becomes 0. For example, '101' becomes '010'.
31+
32+
reverse:
33+
34+
The string is reversed. For example, "001" becomes "100".
35+
36+
Please follow the rule as below:
37+
38+
S0 = ""
39+
S1 = "0"
40+
S2 = "001"
41+
S3 = "0010011"
42+
43+
SN = SN-1 + '0' + switch(reverse(SN-1))
44+
45+
My notes: ok. Defined by a recursive recurrence relation. switch means 1s-complement.

# 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

18+

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>`.
