Check if a Number is Binary

Determine if a given string of integers bin represents a valid binary number. Return 'true' if the string represents a valid binary number, otherwise return 'false'. A binary number is strictly composed of the digits 0 and 1.

Input:

The first line contains an integer ‘T’ representing the number of test cases. Each of the next ‘T’ lines contains a single string ‘bin’.

Output:

For each test case, output a boolean: 'true' if the string is a valid binary number and 'false' otherwise. Each result should be printed on a separate line.

Example:

Input:

3 101 123 110110

Output:

true false true

Constraints:

1

Input:

Output:

true
false
true

Constraints:

1 <= T <= 50
1 <= length(bin) <= 10^4

Note:

No need to print anything; only implement the function to return the desired output.

Accepted Answer

Check if a given string represents a valid binary number composed of 0s and 1s.

Iterate through each character in the string and check if it is either '0' or '1'.
If any character is not '0' or '1', return 'false'.
Return 'true' if all characters are '0' or '1'.
