Add Hashtables: Simple Merge Tutorial

To add two hashtables together, you first need to iterate through one hashtable and then add each key-value pair to the other hashtable. If two hashtables have the same key, their values will be added together. Here is an example code implementation:

def add_hashtables(ht1, ht2):
    result = ht1.copy()
    
    for key, value in ht2.items():
        if key in result:
            result[key] += value
        else:
            result[key] = value
    
    return result

# 两个示例hashtable
ht1 = {'a': 1, 'b': 2, 'c': 3}
ht2 = {'b': 3, 'c': 4, 'd': 5}

# 将两个hashtable相加
result = add_hashtables(ht1, ht2)

print(result)

In the example above, ht1 and ht2 are two hashtables. By using the add_hashtables function, they are combined to create a result hashtable. Finally, the result is printed out.
