Setup

function generateRandomStrings(count, length) {
  const chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
  const result = [];
  for (let i = 0; i < count; i++) {
    let str = "";
    for (let j = 0; j < length; j++) {
      str += chars.charAt(Math.floor(Math.random() * chars.length));
    }
    result.push(str);
  }
  return result;
}

// Example: 100 strings, each ~1000 chars long
const testStrings = generateRandomStrings(100, 1000);
