问题描述:
Write a python function to toggle all even bits of a given number.

测试用例:
['assert even_bit_toggle_number(10) == 0', 'assert even_bit_toggle_number(20) == 30', 'assert even_bit_toggle_number(30) == 20']

生成的代码:
def even_bit_toggle_number(n):
    # Create a mask with all even bits set to 1
    mask = 0xAAAAAAAA  # This is the hexadecimal representation where even bits are set
    # Toggle the even bits using XOR operation
    return n ^ mask
