enumerate

Question

Another technical question on how enumerate works. Can some one explain 
 index({10,30,40,50,60,70},enumerate(5),{}) 
 returns

10; 20; 20; 30; 40 
 Expected out 
 10; 20; 30; 40 
 But same works with below std code , but not sure why? 
 index({10,20,30,40,50,60,70},enumerate(5)+1,{}) 
 output :

10; 20; 30; 40; 50

Syntax 
 enumerate(n)

Returns a list of integer numbers from 0 through n-1 .

Returns : List of Number (Integer)

n (Number (Integer)): The number of integer numbers to return.

Hey ganeshbabuj, I think you may have a typo and just wanted to clarify. You say that index({10,30,40,50,60,70},enumerate(5),{}) returns 20 but there is no 20 in the given list. Did you mean to write that index({10,20,30,40,50,60,70},enumerate(5),{}) is returning 10; 20; 20; 30; 40? This is the result that I got when I ran it. I believe it has something to do with casting {} to an integer. I replaced {} with an integer and it worked as intended. It also works with null. Thanks, Jake

The problem is not in enumerate, it is in third parameter of "index" function. Don't pass null array. problem will be solve.

If you want to write 5 in an enum, so you will get that output

If you can change it so you will get the same output as this
