# Ubuntu |
||||
|
||||
## OS Installation |
||||
|
||||
Download and boot the [last Ubuntu release](http://releases.ubuntu.com/19.04/ubuntu-19.04-desktop-amd64.iso). |
||||
|
||||
Follow the steps : |
||||
|
||||
 |
||||
 |
||||
 |
||||
|
||||
The partitioning is : |
||||
|
||||
- 256 MB : EFI partition |
||||
- 20 GB : system partition |
||||
- 32 GB : unused partition (will be used later) |
||||
- rest : unused partition (will be used later) |
||||
|
||||
 |
||||
 |
||||
 |
||||
|
||||
Remove the installation disk and then reboot. |
||||
|
||||
Skip the welcoming window. |
||||
|
||||
Don't install updates if Ubuntu asks to. The scripts will. |
||||
|
||||
 |
||||
 |
||||
 |
||||
 |
||||
|
||||
## OS configuration |
||||
|
||||
```shell |
||||
student@tmp-hostname:~$ wget github.com/01-edu/public/archive/master.zip |
||||
student@tmp-hostname:~$ unzip master.zip |
||||
student@tmp-hostname:~$ cd public-master/scripts |
||||
student@tmp-hostname:~$ sudo ./install_client.sh |
||||
[...] |
||||
Ask for student user password (will be removed later) |
||||
[...] |
||||
Ask to set the root password |
||||
[...] |
||||
Long installation/configuration process |
||||
[...] |
||||
student@tmp-hostname:~$ cat dconfig.txt | dconf load / |
||||
student@tmp-hostname:~$ reboot |
||||
``` |
||||
|
||||
The system is now read-only, every data is written to a temporary partition. |
||||
|
||||
The session is password-less. |
||||
|
||||
To gain a superuser terminal with read/write access to the filesystem, type these commands: |
||||
|
||||
```shell |
||||
student@tmp-hostname:~$ su - |
||||
Password: |
||||
root@tmp-hostname:~# overlayroot-chroot |
||||
``` |

## brainfuck |
||||
|
||||
### Instructions |
||||
|
||||
Write a Brainfuck interpreter program. |
||||
The source code will be given as first parameter. |
||||
The code will always be valid, with no more than 4096 operations. |
||||
Brainfuck is a minimalist language. It consists of an array of bytes |
||||
(in our case, let's say 2048 bytes) initialized to zero, |
||||
and a pointer to its first byte. |
||||
|
||||
Every operator consists of a single character : |
||||
|
||||
- '>' increment the pointer ; |
||||
- '<' decrement the pointer ; |
||||
- '+' increment the pointed byte ; |
||||
- '-' decrement the pointed byte ; |
||||
- '.' print the pointed byte on standard output ; |
||||
- '[' go to the matching ']' if the pointed byte is 0 (while start) ; |
||||
- ']' go to the matching '[' if the pointed byte is not 0 (while end). |
||||
|
||||
Any other character is a comment. |
||||
|
||||
Examples of outputs : |
||||
|
||||
```console |
||||
student@ubuntu:~/student/brainfuck$ go build |
||||
student@ubuntu:~/student/brainfuck$ ./brainfuck "++++++++++[>+++++++>++++++++++>+++>+<<<<-]>++.>+.+++++++..+++.>++.<<+++++++++++++++.>.+++.------.--------.>+.>." | cat -e |

## doop |
||||
|
||||
### Instructions |
||||
|
||||
Write a program that takes three strings: |
||||
|
||||
- The first and the third one are representations of base-10 signed integers that fit in an int. |
||||
|
||||
- The second one is an arithmetic operator chosen from: `+ - * / %` |
||||
|
||||
- The program must display the result of the requested arithmetic operation, followed by a newline. If the number of parameters is not 3, the program just displays a newline. |
||||
|
||||
- You can assume the string have no mistakes or extraneous characters. Negative numbers, in input or output, will have one and only one leading `-`. The result of the operation fits in an int. |
||||
|
||||
Example of output : |
||||
|
||||
```console |
||||
student@ubuntu:~/piscine/test$ go build |
||||
student@ubuntu:~/piscine/test$ ./test "123" "*" 456 |

## expandstr |
||||
|
||||
### Instructions |
||||
|
||||
Write a program that takes a string and displays it with exactly three spaces |
||||
between each word, with no spaces or tabs at either the beginning nor the end. |
||||
|
||||
The string will be followed by a newline. |
||||
|
||||
A word is a sequence of alphanumerical characters. |
||||
|
||||
If the number of parameters is not 1, or if there are no words, the program displays |
||||
a newline. |
||||
|
||||
Examples of outputs : |
||||

||||
```console |

## hiddenp |
||||
|
||||
### Instructions |
||||
|
||||
Write a program named hiddenp that takes two strings and that, if the first string is hidden in the second one, displays 1 |
||||
followed by a newline, otherwise it displays 0 followed by a newline. |
||||
|
||||
Let s1 and s2 be strings. It is considered that s1 is hidden in s2 if it is possible to |
||||
find each character from s1 in s2, **in the same order as they appear in s1.** |
||||
|
||||
If s1 is an empty string it is considered hidden in any string. |
||||
|
||||
If the number of parameters is not 2, the program displays a newline. |
||||
|
||||
Example of output : |
||||
|
||||
```console |
||||
student@ubuntu:~/student/hiddenp$ go build |

## itoa |
||||
|
||||
### Instructions |
||||
|
||||
- Write a function that simulates the behaviour of the `Itoa` function in Go. `Itoa` transforms a number represented as an`int` in a number represented as a `string`. |
||||
|
||||
- For this exercise the handling of the signs + or - **does have** to be taken into account. |
||||
|
||||
## Expected function |

func Itoa(n int) string { |

## itoabase |
||||
|
||||
### Instructions |
||||
|
||||
Write a function that: |
||||
|
||||
- converts an integer value to a string using the specified base in the argument |
||||
- and then returns this string |
||||
|
||||
The base is expressed as an integer, from 2 to 16. The characters comprising |
||||
the base are the digits from 0 to 9, followed by uppercase letters from A to F. |
||||
|
||||
For example, the base `4` would be the equivalent of "0123" and the base `16` would be the equivalent of "0123456789ABCDEF". |
||||
|
||||
If the value is negative, the resulting string has to be preceded with a |
||||
minus sign `-`. |
||||
|
||||
### Expected function |
||||
|
||||
```go |
||||
func ItoaBase(value, base int) string { |

### Instructions |
||||
|
||||
Write the function ReverseRange which must: |
||||
|
||||
- allocate (with make()) an array of integers. |
||||
- fill it with consecutive values that begin at `end` and end at `start` (Including `start` and `end` !) |
||||
- finally return that array. |
||||
|
||||
### Expected function |
||||
|
||||
```go |
||||
func ReverseRange(start, end int) []int { |
||||
|
||||
} |
||||
``` |
||||
|
||||
Examples of output : |
||||
|
||||
- With (1, 3) the function will return an array containing 3, 2 and 1. |
||||
- With (-1, 2) the function will return an array containing 2, 1, 0 and -1. |
||||
- With (0, 0) the function will return an array containing 0. |
||||
- With (0, -3) the function will return an array containing -3, -2, -1 and 0. |

## reversestrcap |
||||
|
||||
### Instructions |
||||
|
||||
Write a program that takes one or more strings and that, **for each argument**: |
||||
-puts the last character of each word (if it is a letter) in uppercase and the rest |
||||
in lowercase |
||||
-then it displays the result followed by a `\n`. |
||||
|
||||
A word is a sequence of alphanumerical characters. |
||||
|
||||
If there are no parameters, the program displays a `\n`. |
||||
|
||||
Examples of outputs : |
||||
|
||||
```console |
||||
student@ubuntu:~/student/reversestrcap$ go build |
||||
student@ubuntu:~/student/reversestrcap$ ./reversestrcap "First SMALL TesT" | cat -e |
