-// In most of the examples so far, the inputs are known at compile
-// time, thus the amount of memory used by the program is fixed.
-// However, if responding to input whose size is not known at compile
-// time, such as:
-//  - user input via command-line arguments
-//  - inputs from another program
-//
-// You'll need to request memory for your program to be allocated by
-// your operating system at runtime.
-//
-// Zig provides several different allocators. In the Zig
-// documentation, it recommends the Arena allocator for simple
-// programs which allocate once and then exit:
-//
-//     const std = @import("std");
-//
-//     // memory allocation can fail, so the return type is !void
-//     pub fn main() !void {
-//
-//         var arena = std.heap.ArenaAllocator.init(std.heap.page_allocator);
-//         defer arena.deinit();
-//
-//         const allocator = arena.allocator();
-//
-//         const ptr = try allocator.create(i32);
-//         std.debug.print("ptr={*}\n", .{ptr});
-//
-//         const slice_ptr = try allocator.alloc(f64, 5);
-//         std.debug.print("ptr={*}\n", .{ptr});
-//     }
-
-// Instead of an simple integer or a constant sized slice, this
-// program requires a slice to be allocated that is the same size as
-// an input array.
-
-// Given a series of numbers, take the running average. In other
-// words, each item N should contain the average of the last N
-// elements.
