Attention!

Your solution 247972513 for the problem 1923B significantly coincides with solutions arpitsingh9631/247955412, Anjk/247956059, Klinton/247956800, riciw84142/247963622, NR_Nilay2002/247972513, Fatima526/247974223. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.
