// Import std.stdio
import std.stdio;
import std.algorithm;

void main(string[] args) {
// Create an array
int[] array1 = [50, 20, 10, 45, 34];
int[] array2 = [0, 1, 2, 3];
string[] array3 = [""];
// Check if the elements are true
writeln(all(array1)); // true
writeln(all(array2)); // false
writeln(all(array2)); // false
}Checking if the elements of an array are true
