Problem Statement The problem “Write a function to get the intersection point of two Linked Lists” states that you are given two linked lists. But they are not independent linked lists. They are connected at some point. Now you need to find this point of intersection of these two lists. …
Problem Statement The problem “Newman-Conway Sequence” states that you are given an input integer “n”. Then you need to print first nth element of the Newman-Conway Sequence. Example n = 6 4 n = 10 6 Explanation Since the output elements represent the sixth and tenth element of the Newman-Conway …
You are given a sequence of some brackets subsequence, in other words, you are given brackets like ‘(’ and ‘)’ and you are given a query range as a starting point and ending point. The problem “Range Queries for Longest Correct Bracket Subsequence” asks to find out the maximum length …
You are given an array of integers. The integers are only 0 and 1 in the input array. The problem statement asks to find out the largest sub-array that can have equal count of 0s and 1s. Example arr[]={0,1,0,1,0,1,1,1} 0 to 5 (total 6 elements) Explanation From the array position …
You are given a binary array, which consists of 0 initially and Q number of queries. The problem statement asks to toggle the values (converting 0s into 1s and 1s into 0s). After the Q queries performed, print the resultant array. Example arr[] = {0, 0, 0, 0, 0} Toggle(2,4) …
Problem Statement The problem “Delete Nth node from the end of the given linked list” states that you are given a linked list with some nodes. And now you need to remove nth node from the end of the linked list. Example 2->3->4->5->6->7 delete 3rd node from last 2->3->4->6->7 Explanation: …
Problem Statement The problem “Print Fibonacci sequence using 2 variables” states that you need to print the Fibonacci sequence but there is a limitation of using only 2 variables. Example n = 5 0 1 1 2 3 5 Explanation The output sequence has the first five elements of the …
Problem Statement The problem “Non-overlapping sum of two sets” states that you are given two arrays as input values as arrA[] and arrB[] of the same size n. Also, both of the arrays have distinct elements individually and some common elements. Your task is to find out the total sum …
Problem Statement The problem “Find all pairs (a, b) in an array such that a % b = k” states that you are given an array of integers and an integer value called k. The problem statement asks to find out the pair in such a way that that x …
Problem Statement The problem “Range LCM Queries” states that you have an integer array and q number of queries. Each query contains the (left, right) as a range. The given task is to find out the LCM(left, right), i.e, LCM of all the number that comes in the range of …
