#LeetCode: Course Schedule

Also Check: Solutions Of May LeetCoding Challenge (2020)

There are a total of numCourses courses you have to take, labeled from 0 to numCourses-1.

Some courses may have prerequisites, for example to take course 0 you have to first take course 1, which is expressed as a pair: [0,1]

Given the total number of courses and a list of prerequisite pairs, is it possible for you to finish all courses?

Example 1:
Input: numCourses = 2, prerequisites = [[1,0]]
Output: true
Explanation: There are a total of 2 courses to take.
             To take course 1 you should have finished course 0. So it is possible.

Example 2:
Input: numCourses = 2, prerequisites = [[1,0],[0,1]]
Output: false
Explanation: There are a total of 2 courses to take.
             To take course 1 you should have finished course 0, and to take course 0 you should
             also have finished course 1. So it is impossible.

Constraints:
The input prerequisites is a graph represented by a list of edges, not adjacency matrices. Read more about how a graph is represented.
You may assume that there are no duplicate edges in the input prerequisites.
1 <= numCourses <= 10^5

#SpringSecurity: What is the difference between access and refresh token?

ALSO CHECK: Spring Interview Questions and Answers

Access Token

• An access token is a string representing an authorization issued to the client. Tokens represent specific scopes and duration of access, granted by the resource owner, and enforced by the resource server and authorization server.
• An access token is put in the Authorization header of our request and it usually looks like 'Bearer h090Yuuyuiyv'. It is verified by the API, which the client is calling.
• Access token are usually in JWT format, but you can use any other format.
• Access tokens are usually short lived, because it is difficult (although not impossible) to centrally revoke access tokens.
• The responsibility of access token is to access data before it gets expired.
