Traverse the linked list in pairs of three and reverse each pair.
Update the head of the linked list to the new head after reversing each pair.
Return the new head of the linked list.
Search a number in sorted rotated array.
Use binary search to find the pivot point where the array is rotated
Determine which half of the array the target number may be in
Perform binary search on the appropriate half of the array to find the target number
I applied via Walk-in and was interviewed before Jun 2021. There were 2 interview rounds.
Public vs Govt sector
I applied via Campus Placement and was interviewed before Apr 2021. There were 2 interview rounds.
There were many sections.

Next one was of sliding window with little variation , medium difficulty.
Lastly was a section with hr type of questions.
I applied via Campus Placement and was interviewed before Apr 2020. There were 3 interview rounds.
Find frequency of 2 in sorted array of integers in log(n) time.
Use binary search to find first and last occurrence of 2 in array.
Calculate frequency by subtracting last index from first index and adding 1.
Time complexity is O(log(n)).
Find the maximum frequency integer to the right of each index in an array of numbers.
Create a frequency map of the array.
Iterate through the array and for each index, find the maximum frequency integer to the right using the frequency map.
If there are no integers to the right, return -1.
Very impressive able to solve 100 coding questions within 10 mins
Find the minimum string in an array of strings.
Iterate through the array and compare each string to find the minimum.
Use a built-in function like sort() to sort the array and then return the first element.
Consider using a loop to compare each element with the current minimum.
Find the maximum value in an array of strings.
Convert the strings to numbers if needed before finding the maximum value.
Use a loop to iterate through the array and compare each element to find the maximum value.
I applied via Campus Placement and was interviewed before Oct 2023. There were 3 interview rounds.
First round was a aptitude test of 25 question
Oops concept in Java refers to Object-Oriented Programming principles like inheritance, encapsulation, polymorphism, and abstraction.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation involves bundling data and methods that operate on the data into a single unit.
Polymorphism allows objects to be treated as instances of their parent class.
Abstraction hides the implementation d...
Code to create a pattern and explain each line of code
Start by defining the number of rows and columns in the pattern
Use nested loops to iterate through each row and column
Decide the pattern you want to create and use conditional statements to determine the output for each position
I applied via Recruitment Consulltant and was interviewed in Dec 2023. There was 1 interview round.
The order of execution refers to the sequence in which instructions or operations are executed in a program.
The order of execution is determined by the programming language and the specific code being executed.
Generally, code is executed line by line from top to bottom.
However, there are exceptions such as loops, conditionals, and function calls that can alter the order of execution.
In some programming languages, there...
