I can't bring myself to see editorials. At least not before I have solved a problem. Of around 700 problems I solved, I have seen editorials less than ten times. So it takes a lot of time for me to solve hard problems, lasting usually from 2-3 hours to a few days, and sometimes a few months. Now, it is quite inefficient, but I still want to rely on editorials/tutorials as less as possible. Relying on editorials ruin my experience and interest. How can I improve my efficiency without relying on editorials

The problem I am trying to solve has constraints as given, 1 <= q, x <= 4 * 10^5 The time complexity of the solution I have submitted is around O(2 * q). It's basically a linear time solution.

My expectation was that the highest time it would take would be around 100-200 ms. But the solution took around 1200 ms at worst case. Which is far higher than I expected. What is the reason behind this high time complexity

I have been getting runtime error on test case 41. I have been trying to figure out the cause, even rewrote my code, but can't seem to understand why I am getting the error. Here's my code 150627419
