RCCB stands for Residual Current Circuit Breaker. It works on the principle of detecting imbalance in current flow to prevent electric shocks.
RCCB continuously monitors the current flowing through the live and neutral wires.
If there is an imbalance in the current flow, indicating a leakage to ground, the RCCB trips and disconnects the circuit.
It provides protection against electric shocks and fires caused by faulty app...

Its a zoom call interview which lasted for 45 minutes. initially there are two panel members in which one is very targetting at me. They asked me different type of questions like jumping from DSA to project then to python then again java. Its a mixed combo pack type interview. for each and every question they asked me the real time example. The discussion on my project lasted for 15-20 mins.

Count the total number of set bits in the binary representation of numbers from 1 to N modulo 1e9+7.
Use bitwise operations to count the set bits in each number from 1 to N.
Keep track of the total set bits and return the result modulo 1e9+7.
Optimize the solution to handle large values of N efficiently.
Consider using dynamic programming or precomputing values for faster computation.

Public speaking can make me nervous and I may need to practice more to feel confident.
Delegating tasks can be difficult for me because I like to have control over the outcome, but I am working on trusting others to ha
I appeared for an interview in Sep 2017.
Use bitwise operations to find the sum of two numbers without using mathematical operators.
Use bitwise XOR to find the sum of two numbers without carrying.
Use bitwise AND and left shift to find the carry.
Repeat the process until there is no carry left.
