Sorting large array

which compiler should I use to sort an array of size 300000 as my compiler is not giving output for such big input

@mohitshendre2609 it will run on the site just declare array like a[size]
@mohitshendre2609 also why you need to sort such a large array i think nlogn will barely sort it so use inbuilt sort

which sort should i use to sort such a big array

@mohitshendre2609 quicksort or inbuilt stl(sort function)
