Sharpener Interview Questions, Process, and Tips

Java is an object-oriented language while C is a procedural language.

• Java is platform-independent while C is platform-dependent.

• Java has automatic garbage collection while C requires manual memory management.

• Java has built-in support for multithreading while C requires external libraries.

• Java has a larger standard library compared to C.

• Java is more secure than C due to its strong type checking and exception handling.

• C ...read more

Pointers are variables that store memory addresses of other variables in programming languages.

• Pointers allow direct access and manipulation of memory locations.

• They are commonly used in programming languages like C and C++.

• Pointers can be used to pass variables by reference, allowing modifications to the original value.

• They can also be used to dynamically allocate memory.

• Example: int* ptr; // declares a pointer to an

Yes, I know C language. Here's a program to print numbers from 1 to 10 excluding 5.

• Use a loop to iterate from 1 to 10

• Inside the loop, check if the current number is equal to 5

• If it is not equal to 5, print the number

The question was about finding the average of a set of numbers.

• I approached the problem by first summing all the numbers in the set.

• Then, I divided the sum by the total number of elements in the set to find the average.

• I used a loop to iterate through the set and keep track of the sum and count of elements.

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.
