The card shuffling problem involves randomly rearranging a deck of cards.

• Use a random number generator to shuffle the cards

• Implement a shuffling algorithm like Fisher-Yates

• Ensure that all cards have an equal chance of being in any position

Binary search is a search algorithm that finds the position of a target value within a sorted array.

• The array must be sorted in ascending order for binary search to work.

• The algorithm compares the target value with the middle element of the array and narrows down the search range.

• If the middle element is equal to the target, the search is successful.

• If the middle element is greater than the target, the search continues on the left half of the array.

• If the middle element is sm...read more

I solve design issues by conducting user research, collaborating with stakeholders, iterating on designs, and testing prototypes.

• Conduct user research to understand user needs and pain points

• Collaborate with stakeholders to gather feedback and align on goals

• Iterate on designs based on feedback and testing results

• Test prototypes with users to validate design decisions

Binary search using recursion on a linked list

• Create a recursive function to search for the target value in the linked list

• Divide the linked list into two halves and recursively search in the appropriate half

• Base case: return null if the linked list is empty or the target value is not found

My design process involves research, ideation, prototyping, testing, and iteration to create user-centered solutions.

• Research: Understand user needs and business goals

• Ideation: Brainstorm and generate design concepts

• Prototyping: Create interactive prototypes for testing

• Testing: Gather feedback from users and iterate on designs

• Iteration: Refine designs based on feedback and data
