Is 1,5 seconds enough for O(10^10) in c++?

It depends on the operations the solution is doing.

Very roughly, $$$10^8$$$ operations can be done in 1 second. $$$\frac{10^{10}}{10^8} = 100$$$, so $$$10^{10}$$$ operations would take about 100 seconds.

The actual time it takes may vary and its better to have a good understanding about how the time complexity and execution time form.

    but if it will be 2 seconds it will be AC so how do you explain this?

      Maybe the complexity was calculated incorrectly. Also maybe pragmas and optimizations could change the execution time. Can you provide an example of $$$10^{10}$$$ solution getting AC?
