Hi guys, Im having a promblem about the number, but I haven't solved. PLS Help me. The problem is: Given an array a (length 2e5) of positive integer numbers. Chose a subsequence from L to R (1 < L <= R < n) Delete all the number from Al -> Ar. Find the max average of the left nums.

Sample INPUT 5 5 1 7 8 2 Sample OUTPUT 2.667

2 subtask: n <= 1e3 and n <= 1e5 I solve the first one, but not the latter.
