Here's what we found in our archives! Presenting Gennady Korotkevich & Borys Minaiev, the Champions of SnackDown 2019! The qualifiers for SnackDown 2021 will start in 9 days. So go & register if you haven’t already: https://bit.ly/3a87prH, & experience the thrill and glory of the biggest coding competition of the year.

The MEX (minimum excluded) of an array is the smallest non-negative integer that does not belong to the array.
You are given an array A of length N. You create a list B consisting of the MEX-es of all subarrays of the array A. Formally, for all pairs (l, r) such that 1 <= l <= r <= N, you calculate MEX(A_l, A_{l + 1}, ..., A_r) and append the value in the list B. Find the K-th smallest value in the list B: https://bit.ly/3alt937.

Just a few more days for the globally renowned challenge, SnackDown 2021 to begin! Are you ready for the ultimate race? Go, register now: https://bit.ly/3DycXbJ, if you haven’t already.

Here’s the second class of Binary Search Algorithms with Arsh Goyal: https://bit.ly/3AjiGji. Today, he will discuss interview problems on this topic and solve them with you as well. So don’t forget to tune in at 10:30 PM and learn with us.

There are many reasons why you should not miss SnackDown 2021: https://bit.ly/3DycXbJ. Ilya and Artem from ITMO, St. Petersburg, Russia, are telling you why you should register for SnackDown. Only 8 more days left for the Qualifiers to begin! Registration ends on October 19th.

Given an array C of M integers and a square matrix A (with integer entries) of dimension N X N, verify whether the following equation is true,
(C_0 I_{N} + C_1 A + C_2 A^2 + ... C_{M-1} A^{M-1} \equiv 0_N) % 998244353
where 0_N is the square null matrix (matrix in which all elements are zero) and I_N is the identity matrix, both having dimensions N X N: https://bit.ly/3AkbGTe.

With only a week left, the Qualifier is just around the corner: https://bit.ly/2Ys9JH7, and it’s time to ramp up your preparation for SnackDown 2021. Register now: https://bit.ly/3FoAqO7!!
