#SpringSecurity: OAuth2 Implementation with Spring Boot

ALSO CHECK: Spring Interview Questions and Answers

In this tutorial we will learn to build an authorization server using oauth2 to authenticate user's identity to provide access_token. This access_token will be used to request data from resource server.

We will be creating an authorization server and embedding the resource server inside authorization server. Authorization server will generate the tokens and resource server will validate these token.

We will be having two services, first one would be authorization server (along with resource server) and the second one would be a client, from which we will be accessing the servers.

#Ramayan: क्या राम ने खाये थे शबरी के झूठे बेर?

रामानंद सागर की रामायण में शबरी के राम मिलान वाला एपिसोड Youtube पे देख रहा था। रामानंद जी ने रामकथा बहुत साफ़, सहज, और दिल छू लेने वाले भाव से बनायी है, पर शबरी वाला एपिसोड थोड़ा थोड़ा आँखों में चुबता है।

शबरी कहती है "हे राम मुझे नीच कुल में उत्त्पन ये शरीर छोड़ने की आज्ञा देने से पहले मुझे भक्ति का ज्ञान प्रदान करो प्रभु।" उसके बाद राम शबरी को नवदा भक्ति के बारे में बताते है।

रामानंद की रामायण के मखमली क़ालीन जैसी लगती है। शबरी का बार बार खुद को 'नीच' कहने वाले संवाद इस मखमली क़ालीन पर टाट के पैबंद जैसे लगते है।

#LeetCode: First Unique Character in a String

#LeetCode: Max Consecutive Ones

Given a binary array, find the maximum number of consecutive 1s in this array.

Example 1:
Input: [1,1,0,1,1,1]
Output: 3

Explanation: The first two digits or the last three digits are consecutive 1s. The maximum number of consecutive 1s is 3.

Note:
The input array will only contain 0 and 1.
The length of input array is a positive integer and will not exceed 10,000

#LeetCode: Number Complement

Also Check: Solutions Of May LeetCoding Challenge (2020)

Given a positive integer, output its complement number. The complement strategy is to flip the bits of its binary representation.

Example 1:
Input: 5
Output: 2
Explanation: The binary representation of 5 is 101 (no leading zero bits), and its complement is 010. So you need to output 2.

#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.

#SpringSecurity:Oauth 2.0 Roles

ALSO CHECK: Spring Interview Questions and Answers

OAuth 2 is an authorization method to provide access to protected resources over the HTTP protocol.

It enables a third-party application to obtain limited access to an HTTP service:
a). Either on behalf of a resource owner by orchestrating an approval interaction between the resource owner and the HTTP service
b). Or by allowing the third-party application to obtain access on its own behalf.

#LeetCode: Jewels and Stones

Also Check: Solutions Of May LeetCoding Challenge (2020)

You're given strings J representing the types of stones that are jewels, and S representing the stones you have.  Each character in S is a type of stone you have.  You want to know how many of the stones you have are also jewels.

The letters in J are guaranteed distinct, and all characters in J and S are letters. Letters are case sensitive, so "a" is considered a different type of stone from "A".

#Ramayan: कैसे हुआ था सीता का जन्म?

आज बैसाख मास के शुक्ल पक्ष की नवमी तिथि है, पौराणिक ग्रंथों के अनुसार आज के दिन सीता की उत्पत्ति हुई थी।

आज कही पढ़ा 'धार्मिक मान्यता है कि इस दिन प्रभु श्रीराम और माता जानकी को विधि-विधान पूर्वक पूजा आराधना करने से व्रती को अमोघ फल की प्राप्ति होती है साथ ही व्रती को मनोवांछित फलों की भी प्राप्ति होती है'। 

थोड़ा हास्यास्पद लगा, जन्मदिन सीता का और पूजा राम के साथ? बताये ज़रा क्या ऐसी कोई धार्मिक मान्यता है जो कहती हो राम नवमी के दिन राम-सीता की पूजा या फिर जन्माष्टमी के दिन कृष्णा के साथ राधा की आराधना करना चाहिए? खैर जाने दीजिये, पुरुष प्रधान समाज में ऐसा मुमकिन कहा?

कभी समय मिले तो वाल्मीकि रामायण पढ़ियेगा, पुरुष प्रधानता की अनेक मिसाल मिल जायेगी।

शायद इसीलिए वाल्मीकि जी ने सर्ग ६६(छियासठ) में सिर्फ दो श्लोको (१३-१४) में सीता की उत्पत्ति के बारे में संक्षेप में वर्णन किया है, हलाकि राम जन्म विस्तार में बताया गया है।

#LeetCode: First Bad Version

Also Check: Solutions Of May LeetCoding Challenge (2020)

You are a product manager and currently leading a team to develop a new product. Unfortunately, the latest version of your product fails the quality check. Since each version is developed based on the previous version, all the versions after a bad version are also bad.

Suppose you have n versions [1, 2, ..., n] and you want to find out the first bad one, which causes all the following ones to be bad.

You are given an API bool isBadVersion(version) which will return whether version is bad. Implement a function to find the first bad version. You should minimize the number of calls to the API.
