K digit elementsGiven a list of tuples, extract all tuples having K digit elements.Constraints:NAExample:Input :554 234 55222 2312 45782 Output :[(34, 55), (12, 45), (78,)] Explanation:All tuples have numbers with 2 digits.

The problem is asking to extract all tuples from a list that have elements with K digits. Here is a step-by-step solution in Python:

1. First, define a function that takes a list of tuples and an integer K as input.

def extract_tuples(lst, K):

2. Initialize an empty list to store the tuples that meet the condition.

    result = []

3. Iterate over each tuple in the list.

    for tup in lst:

4. For each tuple, iterate over its elements.

        for num in tup:

5. Check if the number of digits in the current element is equal to K. You can convert the number to a string and use the len() function to get the number of digits.

            if len(str(num)) == K:

6. If the condition is met, append the tuple to the result list. To avoid duplicates, check if the tuple is not already in the result list before appending.

                if tup not in result:
                    result.append(tup)

7. After iterating over all tuples, return the result list.

    return result

The complete function is:

def extract_tuples(lst, K):
    result = []
    for tup in lst:
        for num in tup:
            if len(str(num)) == K:
                if tup not in result:
                    result.append(tup)
    return result

You can call this function with a list of tuples and an integer K to get the desired output. For example:

print(extract_tuples([(554, 234), (55222,), (2312, 45782)], 2))  # Output: [(234, 554), (45782,)]
