What's the problem in my code

#1

https://ide.codingblocks.com/s/269684.
I’m first calculating fib of every number in the array, and replacing the given array value with the fib value I got. then I’m building a segment tree for the range query and at last I’m outputting the value of gcd in the l to r range

@aryan fib of 10^9 is very large and will get out of bound therefore find fib%mod in the fib array
