hello @CODER_JATIN

a) u r not taking input correctly , u are given input as interger , char array will not work here.

b) ur code is also considering empty subset but empty subset is not allowed so handle that as well

bhaiya , thodi help karna kese karu fir isko.

#8

@CODER_JATIN
generate all subset , then in base case check two conditions
a) generated subset is not empty
b) sum is zero
if these condiitons hold then return true
else
return false

ese bhi to kr skte hai ki agar ek call se true aa gya fir dusri call krne ki jarurat ni hai.

#18

ha aur agar pehle se false aa gya tab dusra call karna jaruri hai
