This is the list of Interview Questions based on Array Data Structure. You must practice these Multiple Choice Questions. This will help you master Array Coding Questions for Interviews at companies like Google and Microsoft.
Go through this article to learn more about arrays and practice different coding problems before you attempt the questions:
What is the minimum number of comparisons required to find the largest element in an array of N elements?
What is the minimum number of comparisons to find the 2nd largest element provided you have found the largest element?
In Array Data Structure, what is the biggest limitation?
In Dynamic Array, what is the worst case Time Complexity of inserting an new element?
If we have N elements, what is the maximum size of the Dynamic Array?
What is the average case Time Complexity to delete a specific element in an array?
How is an N-dimensional array stored in memory?
To move all negative numbers to the front of array, how many traversals are needed?
Array was improved by Dynamic Array. Dynamic Array is improved by?
What is the Time Complexity to create Suffix Array?
Using Rolling Hash technique in array, the time complexity to find the hash of a sub-array is?
Which data structure is used to find the least frequent element in an array?
Which Algorithm is used to find the largest sub-array sum in optimal time O(N)?
Boyer Moore voting algorithm is used to find the majority element among the given sequence of elements in an array which occurs more than N/2 times. What is the Time Complexity provided space complexity is O(1)?
If there are 1024 elements and we have found the largest element, how many comparisons are needed to find the 2nd largest element?
With these questions (with answers) at OpenGenus, you must have a strong idea of Array and good practice of Coding Interview Porblems. Best of luck for your Coding Interview.
