You are given an unsorted array containing ‘N’ integers. You need to find ‘K’ largest elements from the given array. Also, you need to return the elements in non-decreasing order.

You are given some information about the rooms of a military camp. The rooms are numbered from 0 to 'N-1'. Each room contains keys to some other rooms. You can visit a room only if you have a key to that room. Your task is to determine whether each room can be visited or not.

Note:

1. Room 0 is the only room that is initially unlocked and doesn’t require any key to enter.

2. Any other room can be visited only if you have the key to that room.

3. More than one room can have keys to the same room.

4. You are allowed to visit rooms in any order.

5. You can visit any room multiple times.

You are given an array 'arr' of length 'n', consisting of integers.

A subarray is a contiguous segment of an array. In other words, a subarray can be formed by removing 0 or more integers from the beginning and 0 or more integers from the end of an array.

Find the sum of the subarray (including empty subarray) having maximum sum among all subarrays.

The sum of an empty subarray is 0.

Example :

Input: 'arr' = [1, 2, 7, -4, 3, 2, -10, 9, 1]

Output: 11

Explanation: The subarray yielding the maximum sum is [1, 2, 7, -4, 3, 2].

You have been given a string STR and a non-empty string PTR. Your task is to find all the starting indices of PTR’s anagram in STR.

An anagram of a string is another string which contains the same characters and is obtained by rearranging the characters.

For example: ‘SILENT’ and ‘LISTEN’ are anagrams of each other. ‘ABA’ and ‘ABB’ are not anagram because we can’t convert ‘ABA’ to ‘ABB’ by rearranging the characters of particular strings.

Note:

1. Both STR and PTR consist of English uppercase letters.
2. Length of string 'STR' will always be greater than or equal to the length of string ‘PTR’.
3. In case, there is no anagram substring, then return an empty sequence.
4. In case of more than one anagrams, return the indices in increasing order.
