sir in this ques or rather any other ques concerning arrays what should be the ideal size of the array that we declare .
in this ques at first i had declared the array as arr[1000] and it failed one of the testcases

hello @aaliyah_beg
u dont have to guess the size of array.

u should always declare array like this->
int n;
cin>>n; // first read size of array and then declare array

int a[n] ; // declaring array of size n

#3

sir, but a variable size for an array is not allowed and the size of an array should be static, isnt it?

#4

in dynamic allocation u can change the array size as well(by erasing and allocating new memory check vector implementation for clarity).

yeah array size will be fixed in case of static allocation.
the code that i shared above will work always.
and it neither comes under static allocation nor dynamic , some people say it a pseudo static allocation becuase declarition is compile time but the size will be determined at runtime.
