You are given an array/list ‘BINARYNUMS’ that consists of ‘N’ distinct strings which represent all integers from 0 to N in binary representation except one integer. This integer between 0 to ‘N’ whose binary representation is not present in list ‘BINARYNUMS’ is called ‘Missing Integer’.

Your task is to find the binary representation of that ‘Missing Integer’. You should return a string that represents this ‘Missing Integer’ in binary without leading zeros.

Note

1. There will be no leading zeros in any string in the list ‘BINARYNUMS’.

Example:

Consider N = 5 and the list ‘binaryNums’=  [“0”, “01”, “010”, “100”, “101”].  This list consists of the binary representation of numbers [0, 1, 2, 4, 5]. Clearly, the missing number is 3 and its binary representation will be “11”. So you should return string “11”.

Calculate the final height and duration of flight for a projectile, while the user has to provide values for displacement, initial velocity, and launch angle.

Given an array of numbers, find the maximum sum of any contiguous subarray of the array.

For example, given the array [34, -50, 42, 14, -5, 86], the maximum sum would be 137, since we would take elements 42, 14, -5, and 86.

Given the array [-5, -1, -8, -9], the maximum sum would be -1.

Suppose you have a 3 liter jug and a 5 liter jug (this could also be in gallons). The jugs have no measurement lines on them either. How could you measure exactly 4 liter using only those jugs and as much extra water as you need?

You are given a Binary Tree.

Return the length of the diameter of the tree.

Note :

The diameter of a binary tree is the length of the longest path between any two end nodes in a tree.

The number of edges between two nodes represents the length of the path between them.

Example :

Input: Consider the given binary tree:

Output: 6

Explanation:
Nodes in the diameter are highlighted. The length of the diameter, i.e., the path length, is 6.

You are given two integers, ‘N’ and ‘M’. You are supposed to perform the following operation to convert ‘N’ to ‘M’.

In one operation, you can:

1. Choose any bit in ‘N’.

2. Flip the chosen bit, i.e., if the bit is ‘0’, make it ‘1’ and vice versa.

You are supposed to find the minimum number of operations needed to convert ‘N’ to ‘M’.

You have been given an array/list ‘ARR’ consisting of ‘N’ positive integers. Your task is to return the Next Greater Element(NGE) for every element.

The Next Greater Element for an element ‘X’ is the first element on the right side of ‘X’ in the array 'ARR', which is greater than ‘X’. If no such element exists to the right of ‘X’, then return -1.

For example:

For the given array 'ARR' = [7, 12, 1, 20]

The next greater element for 7 is 12.
The next greater element for 12 is 20. 
The next greater element for 1 is 20. 
There is no greater element for 20 on the right side.

So, the output is [12, 20, 20, -1].
