Calculated columns in pandas can be created using the assign() method or by directly assigning a new column based on existing columns.
Use the assign() method to create calculated columns by specifying the new column name and the calculation formula.
Directly assign a new column by referencing existing columns and applying the desired calculation.
Example: df.assign(new_column = df['column1'] + df['column2'])
Example: df['
Outliers in a dataset can be treated by identifying them using statistical methods and then either removing them, transforming them, or keeping them based on the context.
Identify outliers using statistical methods like Z-score, IQR, or visualization techniques like box plots.
Decide whether to remove outliers, transform them using techniques like winsorization or log transformation, or keep them based on the context of ...
A normal distribution in a dataset is a bell-shaped curve where the data is symmetrically distributed around the mean.
Data is evenly distributed around the mean
68% of data falls within one standard deviation of the mean
95% of data falls within two standard deviations of the mean
Examples: heights of people, test scores in a class
Treating categorised values based on frequency involves grouping rare values together.
Identify rare values based on their frequency distribution
Group rare values together to reduce complexity
Consider creating a separate category for rare values

You are given a grid containing oranges where each cell of the grid can contain one of the three integer values:
Find the minimum time required to rot all fresh oranges in a grid.
Use Breadth First Search (BFS) to simulate the rotting process.
Track the time taken to rot all oranges and return -1 if any fresh oranges remain.
Handle edge cases like no fresh oranges or all oranges already rotten.
Consider using a queue to efficiently process adjacent oranges.
Ensure to update the grid with the new state of oranges after each second.
Given a natural number N
, return the sum of all its proper divisors.
A proper divisor of Y
is defined as a number X
such that X < Y
and Y % X = 0
.
T...
Calculate the sum of proper divisors of a given natural number.
Iterate from 1 to sqrt(N) and check for divisors
If a divisor is found, add it to the sum and also add N/divisor if it is not the same as divisor
Return the sum as the result

Given an array ARR
consisting of non-negative integers, rearrange the numbers to form the largest possible number. The digits within each number cannot be changed.
Rearrange the array elements to form the largest possible number by concatenating them.
Sort the array elements in a custom comparator function to get the largest number.
Convert the sorted array elements to strings and concatenate them to form the final number.
Handle cases where the numbers have the same prefix by comparing the concatenated forms.
Tip 1 : Be clear about whatever you have mentioned in resume, don't mention buzz words, because interviewer can go in depth
Tip 2 : Along with DS and Algo, if you have 3-4 months experience or internship experience, then be ready to answer scenario based technical questions like scaling the application that you developed and design concepts that can be used for improving
Tip 3 : Last but most important tip is to be calm through out the whole process ,don't loose hope if any round didn't go well ,if you have explained your thought process there is still chance to procees to next round so keep preparating for next rounds.
