Dynamic Array Hackerrank Create a list, seqList, of N empty sequences, where each sequence is indexed from 0 to N-1. The elements within each of the N sequences also use 0-indexing. Create an integer, lastAns, and initialize it to 0. The 2 types of queries that can be performed on your list of sequences (seqList) are described below: Query: 1 x y Find the sequence, seq, at index …

No matter how big the array is, the user could still have more input. or If the user doesn't have that much input, you have wasted memory.To overcome this problem we use runtime memory allocation. In this article, we will learn about dynamic allocation and dynamic data structures.

Monk loves to preform different operations on arrays, and so being the principal of Hackerearth School, he assigned a task to his new student Mishki. Mishki will be provided with an integer array $$A$$ of size $$N$$ and an integer $$K$$ , where she needs to rotate the array in the right direction by K steps and then print the resultant array. As she is new to the school, please help her to complete the task.
