Write a shortest bijective program from String to Object. You can specify two sets of chars \$C_1\$ and \$C_2\$, both of which consist of at least 4 different chars[1], and define: String: string consisting of only chars in \$C_1\$ [C₁]* Name: non-empty string consisting of only chars in \$C_2\$...

Square chunk my matrix code-golf array-manipulation Your challenge is to write a function/program that takes a matrix m and a number n as input and: Splits the matrix into n by n chunks Replaces each chunk with the most common value in that chunk (In case of a tie, any of the tied values is fine)...

Your challenge is to write a function/program that takes a matrix of integers m and a number n as input and: Splits m into n by n chunks Replaces each chunk with the most common value in that chunk (In case of a tie, any of the tied values is fine). Outputs the resulting matrix. Note: You ca...

Do these points approximately make up a regular n-gon? code-golf geometry The input is a set of integer coordinates. Take them in whatever form you want. The question is: can you draw an n-sided regular polygon with vertices at the specified coordinates? n being the amount of coordinates provided...
