Coding problem3

It was a virtual interview round. The platform consist of an online IDE, Video of Interviewer and a chat window.
Interviewer asked me Tell me about yourself, then programs on patterns , string handling , SQL queries and OOPs concept.
In the End he asked me about my projects and on what project i am currently working. why you want to join DXC. How you got to know about DXC. Do you want to pursue higher education.

1. First Two patterns of Numbers were given and i have to use any language to print those patterns in parallel to explaining my code.

Problem approach

Asked in companies

You are given a string 'STR'. The string contains [a-z] [A-Z] [0-9] [special characters]. You have to find the reverse of the string.

For example:

 If the given string is: STR = "abcde". You have to print the string "edcba".

follow up:

Try to solve the problem in O(1) space complexity.

Problem approach

I used this approach
1. First, convert String to character array by using the built in Java String class method toCharArray().
2. Then, scan the string from end to start, and print the character one by one.

Try solving now

3. DBMS Questions

Write a query for inner join and explain it and also take any tables to perfom inner join on it and why do we use it.

Problem approach

First i wrote the syntax of the inner join query then took example of student table and performed on it
SELECT table1.column1, table2.column2...
FROM table1
INNER JOIN table2
ON table1.common_field = table2.common_field;
