Grokking the Coding Interview Patterns in C++

K Empty Slots

Understand how to identify the earliest day when two bulbs are turned on with exactly k bulbs off between them. Explore problem-solving techniques involving arrays and permutations, and implement efficient solutions in C++ to tackle this pattern in coding interviews.

We'll cover the following...

Statement

You are given nn bulbs arranged in a row, numbered from 11 to nn. Initially, all bulbs are turned off.

Each day, exactly one bulb is switched on. You are given an array, bulbs of length nn where bulbs[i] =x ...
