SDE - 1

We need to answer questions related to Core subjects, DBMS, SQL, OOPS concept, Programming, Behavioral, Leadership Principles and workstyles.

this round is entirely based on MCQ's.
Questions like:-
1) Which unix command is used to redirect the no of characters in a file f1 to a file f2
2) What is the output of below program
3)What is the output of the flow chart program.
4)which unix command that creates a file without contend
5)Choose the correct property of foreign key in SQL?
6)What is the output of the flow chart program.
7)What is the output of the flow chart program.hich command is used to return the reverse data of a file in Unix?
8)Which of these is DDL command?
9)Which unix command is used to display the line that contains the word 'are'

You are given a string 'str' and an integer 'D'. Your task is to rotate the given string left (anticlockwise) and right (clockwise) by 'D' units from the starting index. You are required to return the rotated string.

Example :

The city of Ninjaland is analogous to the unweighted graph. The city has ‘N’ houses numbered from 1 to ‘N’ respectively and are connected by M bidirectional roads. If a road is connecting two houses ‘X’ and ‘Y’ which means you can go from ‘X’ to ‘Y’ or ‘Y’ to ‘X’. It is guaranteed that you can reach any house from any other house via some combination of roads. Two houses are directly connected by at max one road.

A path between house ‘S’ to house ‘T’ is defined as a sequence of vertices from ‘S’ to ‘T’. Where starting house is ‘S’ and the ending house is ‘T’ and there is a road connecting two consecutive houses. Basically, the path looks like this: (S , h1 , h2 , h3 , ... T). you have to find the shortest path from ‘S’ to ‘T’.

For example

In the below map of Ninjaland let say you want to go from S=1 to T=8, the shortest path is (1, 3, 8). You can also go from S=1 to T=8  via (1, 2, 5, 8)  or (1, 4, 6, 7, 8) but these paths are not shortest.

We need to answer questions related to DBMS, SQL, programming, OOPS concept, Leadership Principles, candidate behavioural questions and workstyles.

You have been given a Binary Tree of 'n' nodes, where the nodes have integer values. Your task is to return the In-Order traversal of the given binary tree.

For example :

For the given binary tree:

The Inorder traversal will be [5, 3, 2, 1, 7, 4, 6].
