//
// You are perhaps tempted to try slices on strings? They're arrays of
// u8 characters after all, right? Slices on strings work great.
// There's just one catch: don't forget that Zig string literals are
// immutable (const) values. So we need to change the type of slice
// from:
//
// var foo: []u8 = "foobar"[0..3];
//
// to:
//
// var foo: []const u8 = "foobar"[0..3];
//
// See if you can fix this Zero Wing-inspired phrase descrambler:
const std = @import("std");
pub fn main() void {
const scrambled = "great base for all your justice are belong to us";
const base1: []u8 = scrambled[15..23];
const base2: []u8 = scrambled[6..10];
const base3: []u8 = scrambled[32..];
printPhrase(base1, base2, base3);
const justice1: []u8 = scrambled[11..14];
const justice2: []u8 = scrambled[0..5];
const justice3: []u8 = scrambled[24..31];
printPhrase(justice1, justice2, justice3);
std.debug.print("\n", .{});

std.debug.print("'{s} {s} {s}.' ", .{part1, part2, part3});
