why sir is passing the array by value (i.e. int *a) in every function instead of passing it by reference (i.e. int a[ ]) ?
Recursion - II first occurence
Hello @rahulkumarraj220 it depends on the constraints if it is for normal testing and the test cases are not large then you can pass it by value aswell.
because it will not give you TLE.
however,it is always recommended to pass by reference only.
just keep this in mind:
