Runtime error is an error that occurs during the execution of a program. In contrast, compile-time errors occur while a program is being compiled. Runtime errors indicate bugs in the program or problems that the designers had anticipated but could do nothing about. For example, running out of memory will often cause a runtime error.
And you probably know that python requires more memory compared with other.
You can solve the problem using C++ and if you want to solve it with python than stop using some fact like using nested loop or using too much list or using any module.

The number of elemens of your variable “count” should be larger. Just change your line
count=[0]*100000
for this one:
count=[0]*1000001

thank you,but as per the question the size of n is 10pow5…so why do we need to take 10pow6+1?
You are counting the values of B, that can be as large as 10^6. As the list is 0-indexed you need 10^6 +1 elements
