1. Strict, hard coded, solution:
```
function allgifts()
dg = [] # daily gifts storage
for d in 1:12
d = sum(1:d) # daily gifts from day 1 to 12
push!(dg, d) # storing each day gifts
end
print(sum(dg)) # showing total number of gifts in storage
end

# > allgifts()
# 364
```
2. Generalizing the function for any number of days:
```
# I'll put here my solution (in Julia) on the twelfth day
```
**Meanwhile, I invite you all to post in the comments some solution coded in the programming language of your choice**

2. Generalizing the function for any number of days:

```
function allgifts2(days)
dg = [] # daily gifts storage
for d in 1:days
d = sum(1:d) # daily gifts from day 1 to days
push!(dg, d) # storing each day gifts
end
print(sum(dg)) # showing total number of gifts in storage
end

# There are actually 13 days from 25 Dec to 6 Jan
# Let's add to the list Thirteen puzzlers puzzling
# > allgifts(13)
