hi @manishayadav1360_c0939b9a17f994ff
yes if we directly declare n then no need to do size of a/size of int
its use full when we are given an array of unknown size and we need to compute n…

#3

ok got it sir. sir, but can you clarify that why we use j=n-1; like on declaring part n-1 se kyu hoga ???

#4

j=n-1;
