Viewics Interview Questions and Answers

Explaining something involves breaking down a concept or process into simpler terms for better understanding.

• Start by providing an overview of the topic

• Break down the key components or steps involved

• Use examples or analogies to clarify complex ideas

• Conclude by summarizing the main points

A program to check if a given number is prime or not.

• A prime number is a number that is only divisible by 1 and itself.

• Start checking from 2 up to the square root of the number.

• If the number is divisible by any number in the range, it is not prime.

• Otherwise, it is prime.

• Optimization: check only odd numbers after 2.

Fibonacci program generates a series of numbers where each number is the sum of the two preceding ones.

• The program can be implemented using recursion or iteration.

• The first two numbers in the series are always 0 and 1.

• The next number is the sum of the previous two numbers.

• Example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418,...read more

Flowchart for two programs

• Document the flowchart

Print the level order traversal of binary tree in spiral form

• Perform level order traversal of the binary tree

• Alternate the direction of traversal for each level

• Use a stack to reverse the order of nodes in each level

• Print the nodes in the order of traversal

Find the maximum element in each subarray of size k in a given array.

• Iterate through the array from index 0 to n-k.

• For each subarray of size k, find the maximum element.

• Store the maximum elements in a separate array.

• Return the array of maximum elements.

To find the Kth largest element in two sorted arrays, we can use the merge step of merge sort algorithm.

• Merge the two arrays into a single sorted array using a modified merge sort algorithm.

• Return the Kth element from the merged array.

Merge two sorted arrays into one sorted array with expected time complexity of (m+n).

• Use a two-pointer approach to compare elements from both arrays and merge them into the first array.

• Start comparing elements from the end of both arrays and place the larger element at the end of the first array.

• Continue this process until all elements from the second array are merged into the first array.
