coin flip...showing run time error...please help..!!

my code is giving me the correct output but code chef is showing run time error SIGSEGV…please help me how to remove it…here is my code

Your code is giving RTE because u are making an array of 10^9(of n values of input) which is not possible. The max possible array that you can make is less than 10^7.

In this question brute force would not work. try to make an approximately O(1) approach because here g<=20000 and T<=10, so will be ypur approach you need to apply it 2*10^5 times.

When you declare variable ‘N’ as long , you cannot input as scanf("%ld", &N)."%ld" for long int. :slight_smile:
