def twoSum(nums, target):
    # Create a dictionary to store elements and their indices
    num_dict = {}
    
    # Iterate through the array
    for i, num in enumerate(nums):
        # Calculate the complement (the value needed to reach the target)
        complement = target - num
        
        # Check if the complement exists in the dictionary
        if complement in num_dict:
            # Return the indices of the current number and its complement
            return [num_dict[complement], i]
        
        # If the complement doesn't exist, add the current number and its index to the dictionary
        num_dict[num] = i
    
    # If no solution is found, return an empty list
    return []

# Example usage
nums = [2, 7, 11, 15]
target = 9
result = twoSum(nums, target)
print(result)  # Output: [0, 1] (nums[0] + nums[1] = 2 + 7 = 9)
