2. 解题过程

拿到题目一点思路没有，异性突然想到计算机中的 0 和 1，将上面个两个字符串转为二进制

key.txt:

0110000101110011011000010110010001110011011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011100010111011101100101011100110111000101100110

0000011100011111001000000000001100001000000001000001001001010101000000110001000001010100010110000100101101011100010110000100101001010110010100110100010001010010000000110100010000000010010110000100011000000110010101000100011100000101010101100100011101010111010001000001001001011101010010100001010000011011

然后进行异或：

key = "0110000101110011011000010110010001110011011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011000010111001101100100011100010111011101100101011100110111000101100110"

m = "0000011100011111001000000000001100001000000001000001001001010101000000110001000001010100010110000100101101011100010110000100101001010110010100110100010001010010000000110100010000000010010110000100011000000110010101000100011100000101010101100100011101010111010001000001001001011101010010100001010000011011"

result = ""

for i in range(len(key)):
    if key[i] == m[i]:
        result += "0"
    if key[i] != m[i]:
        result += "1"
print(result)

将结果转为字符串：

3. 所需工具

• utools：戳我💋

4. 写在最后
