Data Structures and Algorithms

Array, Linked List, Stack, Queues, Searching, Sorting, Tree, Graph…

Hi Friends, Do you have questions that why should I study all the above-complicated stuff if it has absolutely no use in real life?? Why companies ask questions related to data structures and algorithms if it’s not useful in a daily job??

A lot of beginners and experienced programmers avoid learning Data Structures and Algorithms because it’s complicated and they think that there is no use of all the above stuff in real life. So before we discuss the topic we are going to throw a simple problem at you and you need to find the solution for that.

Data structures and algorithms play a major role in implementing software and in the hiring process as well. A lot of students and professionals have this question that why these companies’ interviews are focused on DSA instead of language/frameworks/tools specific questions? Let us explain why it happens…

When you ask someone to make a decision for something the good one will be able to tell you “I chose to do X because it’s better than A, B in these ways. I could have gone with C, but I felt this was a better choice because of this“. In our daily life, we always go with that person who can complete the task in a short amount of time with efficiency and using fewer resources. The same things happen with these companies. The problem faced by these companies is much harder and at a much larger scale. Software developers also have to make the right decisions when it comes to solving the problems of these companies.

Knowledge of data structures like Hash Tables, Trees, Trees, Graphs, and various algorithms goes a long way in solving these problems efficiently and the interviewers are more interested in seeing how candidates use these tools to solve a problem. Just like a car mechanic needs the right tool to fix a car and make it run properly, a programmer needs the right tool (algorithm and data structure) to make the software run properly. So the interviewer wants to find a candidate who can apply the right set of tools to solve the given problem... If you know the characteristics of one data structure in contrast to another you will be able to make the right decision in choosing the right data structure to solve a problem.

     TCS APTITUDE PLACEMENT PAPER Q 1.2/3rd of the balls in a bag are blue, the rest are pink. if 5/9th of the blue balls and 7/8th of the pink balls are defective, find the total number of balls in the bag given that the number of non defective balls is 146? a)   216  b)   649  c)   432  d)   578 Solution- let total no of balls =x blue=2x/3 pink=x/3 total no of defective balls = 10x/27 +7x/24 =143x/216 non defective balls=x-143x/216=146 x=432   Q 2. Find no of ways in which 4 particular persons a,b,c,d and 6 more persons can stand in a queue so that A always stand before B. B always stand before C, And C always stand before D. a)6!  b)7!  c)1006*6! d)10046! Solution - a,b,c,d are grouped ie consider them as one and remaining as 6. total 6+1 = 7!

WIPRO APTITUDE PAPER

              WIPRO APTITUDE PAPER 1) In most states in India the law for the sale of alcoholic beverages provides that beer cannot be sold after a certain hour. However, in some States the law permits a customer to consume, after the deadline, what has been sold before the curfew. In a certain bar 2 men ordered sufficient beer to cover their probable requirements in anticipation of the curfew. One man ordered and paid for 5 bottles and the other man ordered and paid for 3 bottles. But as the curfew started, an old friend of both the men approached and requested them to share the eight bottles of beer between them. The friend thanked the two men and put down Rs 8 in payment for the beer he had consumed, asking them to share the money in proportion to the quantity of beer they have contributed to him. How should this money be equitably divided between the two men? a. Rs 7 and Rs 1 b. Rs 6 and Rs 2 c. Rs 5 and Rs 3 d. Rs 4 and Rs 3 Correct Option a Explanation: The three
