Fonctions

Ici je répertorie quelques fonctions que je réutilise pour des exercices ou challenges (quand j'y pense)

Go - Convertir un String en int

import "strconv"

func StringToNumber(str string) int {

n, _ := strconv.Atoi(str)

return n

}

Cpp - Inverser un String

#include <string>

using namespace std ;

string reverseString (string str ){

string result = "";

for(int i = str.size()-1; i >= 0; i--){

result += str[i];

}

return result;

}

Lua - Contains

local contains = {}

function contains.check(a, x)

for index, value in ipairs(a) do

if value == x then

return true

end

return false

end

return contains

Lua - String endswith

endswith = {}

function endswith.strEndsWith(s, ending)

valid = true

print(s, ending)

if #s >= #ending then

dif = #s-#ending

for i=1, #ending do

print(s:sub(i+dif,i+dif),ending:sub(i,i))

if s:sub(i+dif,i+dif) ~= ending:sub(i,i) then

valid = false

end

return valid

else

return false

end

return endswith

Lua - Sudoku

r = true

col = {}

cell = {}

for j=1,9 do

col[j] = ""

cell[j] = ""

end

for i=1,9 do

next_token = io.read()

index = 1

for j=1,17,2 do

col[index] = col[index] .. string.sub(next_token,j,j)

if(i < 4 and index < 4) then

cell[1] = cell[1] .. string.sub(next_token,j,j)

elseif(i < 4 and index > 3 and index < 7) then

cell[2] = cell[2] .. string.sub(next_token,j,j)

elseif(i < 4 and index > 6) then

cell[3] = cell[3] .. string.sub(next_token,j,j)

elseif(i > 3 and i < 7 and index < 4) then

cell[4] = cell[4] .. string.sub(next_token,j,j)

elseif(i > 3 and i < 7 and 3 and index < 7) then

cell[5] = cell[5] .. string.sub(next_token,j,j)

elseif(i > 3 and i < 7 and index > 6) then

cell[6] = cell[6] .. string.sub(next_token,j,j)

elseif(i > 6 and index < 4) then

cell[7] = cell[7] .. string.sub(next_token,j,j)

elseif(i > 6 and 3 and index < 7) then

cell[8] = cell[8] .. string.sub(next_token,j,j)

elseif(i > 6 and index > 6) then

cell[9] = cell[9] .. string.sub(next_token,j,j)

end

index = index + 1

end

if(string.match(next_token,"[1+]") == nil

or string.match(next_token,"[2+]") == nil

or string.match(next_token,"[3+]") == nil

or string.match(next_token,"[4+]") == nil

or string.match(next_token,"[7+]") == nil

or string.match(next_token,"[8+]") == nil

or string.match(next_token,"[9+]") == nil

) then

r = false

end

for i=1,9 do

if(string.match(col[i],"[1+]") == nil

or string.match(col[i],"[2+]") == nil

or string.match(col[i],"[3+]") == nil

or string.match(cell[i],"[9+]") == nil

) then

r = false

end

print(r)

Java - Soustraction de tableau

import java.util.*;

public class TableSubstract{

public static int[] arrayDiff(int[] a, int[] b) {

List<Integer> c = new LinkedList<Integer>(Arrays.stream(a).boxed().toList());

if(b.length > 0){

for(int i = 0; i < b.length; i++){

if(c.contains((Integer)b[i])){

while(c.contains((Integer)b[i])){

c.remove((Integer)b[i]);

}

return c.stream().mapToInt(Integer::intValue).toArray();

}

Java - ASCII Art

import java.util.*;

class Ascii{

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

int L = in.nextInt();

int H = in.nextInt();

in.nextLine();

String T = in.nextLine();

for (int i = 0; i < H; i++) {

String ROW = in.nextLine();

for(int j = 0; j<T.length(); j++)

{

if(T.charAt(j) == 'A' || T.charAt(j) == 'a')

{

for(int l = L-L; l < L; l++)
