There is no 'strings_xor' function in the 'Javascript (Node.js)' mode. Is this a bug? What should I debug in corresponing to the test conditions?

For Python:

def strings_xor(s, t):
    res = ""
    for i in range(len(s)):
        if s[i] == t[i]:
            res = res+'0';
        else:
            res = res+'1';

    return res

For C++, it looks like the submission process is broken for modes C++14/C++20.

Those modes gave wrong answer for code that was successully submitted in C++11 mode!

This function performs a bitwise XOR operation on two input strings s and t.

The XOR operation compares corresponding characters of the two strings:

- If the characters are the same, it appends '0' to the result string.

- If the characters are different, it appends '1' to the result string.

def strings_xor(s, t): res = "" # Initialize an empty result string

# Loop through each character index in the strings (assumes both strings have the same length)
for i in range(len(s)):
    if s[i] == t[i]:  
        res += '0'  # If characters at index `i` are the same, append '0'
    else:
        res += '1'  # If characters at index `i` are different, append '1'

return res  # Return the final XOR result string

Input: Two binary strings from the user

s = input() # First binary string t = input() # Second binary string

Output: The XOR of the two input strings

print(strings_xor(s, t))
