hi there were few minor error

for the case where u are not including the present digit u got to update the sum as sum-=a[i]

I have updated the code:
but here u`ll get a WA since all the combinations are not unique there are duplicate combinations that are being printed, try to remove this by inserting if condition.
In case u are not able to figure out, fell free to ask

maam unable to figure out why for some it is giving duplicate elements and for rest not

#4

those elements that occur more than one in the i/p array give u a duplicate combination
try to do a check on this condition when a[i] == a[i+1] and i > 0 u do not include that combination

ma’am still unable to understand
