Determine the minimum number of integers to be added to an array to make its sum equal to a given value.
Iterate through the array and calculate the current sum.
Determine the difference between the target sum and the current sum.
Add the minimum number of integers within the range of -MAXVAL to MAXVAL to reach the target sum.
Given an array of integers NUMS
consisting of N
integers and an integer K
, determine the maximum sum of an increasing subsequence with exactly K
elements.
Find the maximum sum of an increasing subsequence with exactly K elements in an array of integers.
Iterate through the array and maintain a dynamic programming table to store the maximum sum of increasing subsequences ending at each index.
For each element, check all previous elements to find the increasing subsequence with maximum sum ending at that element.
Update the dynamic programming table with the maximum sum found...

Check if a binary tree is a Complete Binary Tree or not based on given criteria.
Traverse the binary tree level by level and check if all levels are completely filled except the last one.
Ensure all nodes at the last level are positioned at the leftmost side.
Use level order traversal to check for completeness of the binary tree.
Example: For input 1 2 3 4 -1 5 6 -1 7 -1 -1 -1 -1 -1 -1, the output should be 1.
Given an array arr
of N
non-negative integers, determine whether the array consists of consecutive numbers. Return true if they do, and false otherwise.
