Algorithm اسئلة واجوبة المقابلات
سؤال 41. What is the difference between greedy and dynamic programming?
Greedy algorithms make locally optimal choices at each stage with the hope of finding a global optimum, while dynamic programming involves solving subproblems and combining their solutions to solve the overall problem.
سؤال 42. Explain the concept of Big-O notation.
Big-O notation describes the upper bound of an algorithm's time or space complexity in the worst-case scenario. It provides an asymptotic growth rate, ignoring constant factors and lower-order terms.
سؤال 43. What is the Floyd-Warshall algorithm used for?
The Floyd-Warshall algorithm is used for finding the shortest paths between all pairs of vertices in a weighted graph, even if the graph contains negative weight edges.
سؤال 44. Explain the concept of a binary search tree (BST).
A binary search tree is a binary tree where the left subtree of a node contains only nodes with keys less than the node's key, and the right subtree contains only nodes with keys greater than the node's key.
سؤال 45. What is the Knapsack problem?
The Knapsack problem is a combinatorial optimization problem where the goal is to select items with given weights and values to maximize the total value, subject to a constraint on the total weight.
