kandi X-RAY | BigSort Summary

BigSort is a Python library. BigSort has no bugs, it has no vulnerabilities and it has low support. However BigSort build file is not available. You can download it from GitHub.

Sort files which are TeraBytes in Size. Python implementation of merge sort which can be used to sort files as big as TBs. The one of the major problem in sorting is holding the data in memory, so read file serially i.e. read line by line, once considerable amount of lines are obtained sort them in-memory and write to separate file. Continue to read from the main file where we left, do the above process till the file is over. Now we have multiple small files whose content are sorted. In order to merge them as single sorted file, created file read pointer to each small file, compare the content at header and write to final sorted file. A detailed tutorial is available at www.satcos.in/programming/BigSort.php.

QUESTION

Program terminated with signal SIGABRT, Aborted. terminate called after throwing an instance of 'std::out_of_range'

Asked 2021-Jan-07 at 18:38

The question is : Consider an array of numeric strings where each string is a positive number with anywhere from 1 to 10^6 digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array.

As pointed out in the comments, your error originates form your attempt to read a number with many digits (up to a million) into a 64bit number, which can hold all numbers up to 1<<64=18446744073709551616, i.e. no numbers with more than 20 digits.

Hence you must find another way to compare those strings. The question is not very clear about leading zeros, but let us assume that the numbers are represented without leading zeros. Then the std::strings, representing the numbers, can be compared by their size() and, if that is equal, lexicographically, which is implemented by operator< between std::strings, i.e.

QUESTION

HackerRank Big Sorting segmentation Fault in C++

Asked 2020-Feb-07 at 08:23

I have a question about the BigSorting task from HackerRank.

My code successfully runs all tests except 3. (I located files on which my program does not work under the names input03.txt, input04.txt and input05.txt on my google drive. Here is the link to the drive.) https://drive.google.com/drive/u/1/folders/1psno2RbeYXX5ohHjs5BWke6E-K2cJl-3

My program crashes with a "Segmentation fault" error. I’ve been sitting for 2 hours and can’t understand what the mistake is. This is my first question on StackOverflow, so I apologize right away if I did something wrong.

Here is the code.

The function given to std::sort is supposed to induce a strict weak ordering on the elements in the iterator range, see std::sort, Compare requirements and strict weak ordering on wikipedia.

Your isShorter induces an order that is not strict. In particular it does not have the property that isShorter(x, x) == false for all x.

The problem is that you return true when you cannot find either string to come before or after the other in the order, but you should return false.

The function is supposed to model <, not <=.

Whether this is the cause of the segmentation fault is unclear since you haven't given a full code example, but violating the std::sort requirements does cause undefined behavior.
