To find if two linked lists intersect, traverse both lists and compare their tail nodes.
Traverse both linked lists and find their lengths
If the lengths are different, move the longer list's head pointer to the difference in length
Now traverse both lists and compare their nodes until a common node is found
If no common node is found, the lists do not intersect
Program to find the angle between the hands of a clock given the time.
Calculate the angle of the hour hand from 12 o'clock position
Calculate the angle of the minute hand from 12 o'clock position
Calculate the absolute difference between the two angles
If the difference is greater than 180 degrees, subtract it from 360 degrees
Return the absolute value of the difference as the angle between the hands
To check if a string is a palindrome, compare the first and last characters, then move towards the center.
Remove all non-alphanumeric characters and convert to lowercase
Use two pointers, one starting from the beginning and the other from the end
Compare the characters at both pointers, move towards the center until they meet
If all characters match, the string is a palindrome
JOINS are used to combine rows from two or more tables based on a related column between them.
JOINS are used to retrieve data from multiple tables in a single query
There are different types of JOINS - INNER, LEFT, RIGHT, FULL OUTER
JOINS are based on a related column between the tables
Syntax: SELECT * FROM table1 JOIN table2 ON table1.column = table2.column
What people are saying about Flipkart
Combine 4 elements of a sorted array of size 7 and a sorted array of 3 elements to make a sorted array.
