Printing Sub arrays in array

Question

Let array a={1,2,3,4}

Then I store them as arrays like
{1}
{2}
{3}
{1,2}
{2,3}
{3,4}
{1,2,3}
{2,3,4}
{1,2,3,4}

At least tell me how to print numbers like that

You can tell in C

Answer 1

SRI SIVA LAKSHMANA REDDY DWARAMPUDI Here's a possible solution:

from itertools import combinations as k

list = (1, 2, 3, 4)
for i in range(1, len(list)):
print(*map(set, tuple(k(list, i))), sep="\n")
print(set(list))

# Hope this helps

Answer 2

Calvin Thomas yeah thanks 😄
If possible send c approach also

Answer 3

In python you can do

[ a[n:i] for i in range(len(a)+1) for n in range(i) ]

In C the approach is similar (but it depends on how you handle arrays),
loop i from 0 to array lenght
and loop j from 0 to i
and copy the data from a+j to a+i inside the result array (the position in the result array should be i*j + j)
