Task 1 – Enemy wave processing pipeline

Compose a series of functions into a pipeline that processes a list of enemy waves, applying increased difficulty (hard mode), validating the result, and transforming it into a formatted string using the following code:

public class EnemyWave
{
   public int WaveNumber { get; set; }
   public int EnemyCount { get; set; }
   public string Description { get; set; }
}
Func<EnemyWave, bool> validateWave = wave => wave.EnemyCount > 0;
Func<EnemyWave, EnemyWave> applyHardMode = wave =>
{
   wave.EnemyCount = (int)(wave.EnemyCount * 1.2); // +20% enemies
   return wave;
};
Func<EnemyWave, string> formatWave = wave => $"Wave {wave.WaveNumber}: {wave.Description} - {wave.EnemyCount} enemies";
