You have been given an array(ARR) of positive integers and an integer X. You have to find the minimum length subarray such that the sum of all of its elements is strictly greater than the given integer X.

Note:

A subarray is a contiguous block of elements that can be formed by deleting some (possibly zero) elements from the beginning or the end of the original array. 

For example :

If the given array is [1, 2, 3, 4, 5], then [2, 3, 4], [1, 2], [5] are some subarrays while [1, 3], [2, 3, 5] are not.

If there are multiple subarrays with minimum length, find one which appears earlier in the array (i.e. subarray that starts with lower index).

If there is no such subarray, print an empty line.

You are given an array arr of length N. You have to return a list of integers containing the NGE(next greater element) of each element of the given array. The NGE for an element X is the first greater element on the right side of X in the array. Elements for which no greater element exists, consider the NGE as -1.

For Example :

If the given array is [1, 3, 2], then you need to return [3, -1, -1]. Because for 1, 3 is the next greater element, for 3 it does not have any greater number to its right, and similarly for 2.

Ninjas is practicing problems on the linked list. He came across a problem in which he has given a linked list of ‘N’ nodes and two integers, ‘LOW’ and ‘HIGH’. He has to return the linked list ‘HEAD’ after reversing the nodes between ‘LOW’ and ‘HIGH’, including the nodes at positions ‘LOW’ and ‘HIGH’.
