Today’s atcoder too easy

C was pretty simple and not time consuming
E was a very common dp problem
F had a very common segment tree merge pattern

D : I took 4 WA’s coz I was too lazy to fully optimize it but ultimately had to do it

G : didn’t do it but I assume it had something to do with markov chains so too time consuming writing the equations and shit

First ever 6 problems solved in an atcoder contest
