Let's call an array good if there is an element in the array that equals to the sum of all other elements. For example, the array a=[1,3,3,7]a=[1,3,3,7] is good because there is the element a4=7a4=7 which equals to the sum 1+3+31+3+3. You are given an array aa c...

Hello. I can't understand why my solution of D problem isn't working. I told that we can use some kind of greedy algorithm. Let's choose every number from prefix in our array. So if our prefix i isn't available(it's organize not possible situation), so we just don't mark this,...
