Solution

This problem is asking for the number of trailing zeroes in the binary representation of a given integer. Here's how you can solve it:

  1. Convert the integer to binary: In Python, you can use the built-in function bin(). This function converts an integer to a binary string. For example, bin(18) returns '0b10010'.

  2. Count the trailing zeroes: You can do this by reversing the binary string and counting the number of zeroes before the first one. In Python, you can use the str.rfind() method, which returns the last index where the specified substring is found. For example, ('0b10010'[::-1]).find('1') returns 1, which is the number of trailing zeroes in the binary representation of 18.

Here's the Python code that implements these steps:

def count_trailing_zeroes(A):
    # Convert A to binary and reverse the string
    binary = bin(A)[2:][::-1]
    # Find the first '1' in the reversed string
    first_one = binary.find('1')
    # Return the number of trailing zeroes
    return first_one

You can test this function with the provided examples:

print(count_trailing_zeroes(18))  # Output: 1
print(count_trailing_zeroes(8))   # Output: 3

This function works because the binary

Problem DescriptionYou are given a binary string B of length L which contains K ones and remaining zeros. You are required to place the K ones in the binary string in such a way that the longest consecutive zeros have the least length possible. Once such a binary string is constructed, you are required to print the length of the contiguous block of zeros, which has the largest length.Constraints0 <= K <= L1 <= L <= 10^6InputSingle line consisting of two space separated integers denoting L and K.OutputPrint a single integer denoting the length of the longest consecutive zeros as per the problem.Time Limit (secs)1ExamplesExample 1Input3 1Output1ExplanationB is of length 3 and it has 1 one's.So the possible strings as per the problem are 010, 001, 100.In the first case, the maximum length of consecutive zeros is 1 whereas in the other two cases it is 2. Hence the constructed binary string is 010 and the output is 1.Example 2Input3 3Output0ExplanationB is of length 3 and it has all three one's. There is no block of zeros, hence the output is 0.
