- Q1. How we know we that perticular wire is phase or neutral. What is current or voltage
- Ans.
Phase wires carry current while neutral wires complete the circuit. Voltage is the potential difference between two points.
Phase wires are usually colored black, red, or blue while neutral wires are usually colored white or gray.
A voltage tester can be used to determine if a wire is live or not.
Current flows from the phase wire to the load and back to the neutral wire.
Voltage is measured in volts and represents the pot...

- Q1. Given a no K and an array. Find pair of elements whose sum is equal to given no K
- Ans.
Find pair of elements in an array whose sum is equal to a given number K.
Iterate through the array and for each element, check if K minus the element exists in the array.
Use a hash table to store the elements and their indices for faster lookup.

Create a public static method to access the instance
Ensure thread safety by using synchronized keyword or static initialization block
Examples: Logger, Configuration Manager, Database Connection

Logical errors occur when the code runs without errors, but produces unexpected results, such as a miscalculation in a formula.
- Q6. How session works in php?
- Ans.
Session in PHP allows to store user data on the server for later use.
Session starts when a user logs in and ends when the user logs out or the session expires.

Round duration - 90 Minutes
Round difficulty - Hard
I found the online coding round of Flipkart to be quite difficult based on the constraints of the problem and their time limits. I coded the first problem quite easily but on the second and the third problem , my code could only pass a few test cases and gave TLE for most of them. Both the questions required very efficient solution and the last 5 to 10 Test Cases carried more weight than the rest so I didn't get through this round.
