Algorithm: Preprocess string p to get a character frequency difference map. Take a window of size p.length(), and slide it from left to right through s. Each slide has 1 add and 1 deletion operation to the diff map. When a character's diff becomes 0, remove this key from diff map....
Given an arraynums, there is a sliding window of sizekwhich is moving from the very left of the array to the very right. You can only see theknumbers in the window. Each time the sliding window moves right by one position. For example, Givennums=[1,3,-1,-3,5,3,6,7], andk=...
