Missing Number Problem Statement
You are provided with an array named BINARYNUMS
consisting of N
unique strings. Each string represents an integer in binary, covering every integer from 0 to N except for one. Your task is to identify this missing integer and return its binary representation as a string without any leading zeros.
Input:
The first line indicates an integer T
, the number of test cases. Each test case consists of: First line: An integer N
indicating the number of binary strings in BINARYNUMS
. Second line: N
space-separated binary strings representing BINARYNUMS
.
Output:
For each test case, output a single string, representing the binary form of the missing integer without leading zeros. Each test case result should be on a different line.
Example:
Input: N = 5, BINARYNUMS = ["0", "01", "010", "100", "101"] Output: "11" Explanation: The missing number is 3 and its binary representation is "11".
Constraints:
1 <= T <= 50
1 <= N <= 10^4
- Time limit: 1 second.
Note:
Ensure your implementation returns the output without printing to the console, as output handling is already managed.
