Question
Given an integer A, count and return the number of trailing zeroes.Problem Constraints1 <= A <= 109Input FormatFirst and only argument is an integer A.Output FormatReturn an integer denoting the count of trailing zeroes.Example InputInput 1: A = 18Input 2: A = 8Example OutputOutput 1: 1Output 2: 3Example ExplanationExplanation 1: 18 in binary is represented as: 10010, there is 1 trailing zero.Explanation 2: 8 in binary is represented as: 1000, there are 3 trailing zeroes.
Solution
To solve this problem, we need to convert the given integer into binary and then count the number of trailing zeroes. Here is a step-by-step solution in Python:
def count_trailing_zeroes(A):
# Convert the integer to binary and remove the '0b' prefix
binary = bin(A)[2:]
# Reverse the binary string to count trailing zeroes
binary = binary[::-1]
# Initialize count of trailing zeroes
count = 0
# Iterate over the reversed binary string
for bit in binary:
# If the bit is '0', increment the count
if bit == '0':
count += 1
# If the bit is '1', break the loop as we have counted all trailing zeroes
else:
break
# Return the count of trailing zeroes
return count
You can call this function with an integer to get the count of trailing zeroes. For example:
print(count_trailing_zeroes(18)) # Output: 1
print(count_trailing_zeroes(8)) # Output: 3
This function works by first converting the integer to a binary string. It then reverses this string so that the trailing zeroes in the original binary string are now leading zeroes in the reversed string. The function then iterates over the reversed string, counting zeroes until it encounters a '1'. At this point, it has counted all the trailing zeroes in the original binary string, so it breaks the loop and

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.
Given a positive integer num represented as a string, return the integer num without trailing zeros as a string. Example 1:Input: num = "51230100"Output: "512301"Explanation: Integer "51230100" has 2 trailing zeros, we remove them and return integer "512301".Example 2:Input: num = "123"Output: "123"Explanation: Integer "123" has no trailing zeros, we return integer "123".
