It says it has to be resolved in one line "you cannot add or remove lines to the code."

So this was my solution in Javascript, anyway I'm facing the same issue as everyone, it's broken: return input = chunk.split('\n')[0] ^ chunk.split('\n')[1];

I struggled in C++ I tried on C++14 over 20 times but it didn't work. Then I changed to C++11 finally it worked. I cannot understand why this happened. Who please explain this to me.

[string strings_xor(string s, string t) { string res = ""; for(int i=0; i < s.size(); i++) { if(s[i] == t[i]) res += '0'; else res += '1'; } return res; }

Facing issues in Kotlin and Java.

Expected output: 10000 Your output: 10000

Wow!

Works in JAVA 7.

python 3 solution

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

return res

s = input() t = input() print(strings_xor(s, t))
