Arrays-Target Sum Triplets - Printing Problem

#1

My code finds the answer for target-3 but not the target. Please help.

Hi Mayank, that is happening because you’re printing i,j and k instead of a,b and c. Also, there is a problem in your logic in the loops. I’ve corrected the code and you can refer to it here.
