Heyy @tanjuljain19,
I have made small changes from line 223. Kindly compare the codes and understand your mistakes. They were very silly errors and should be avoided in the future. https://ide.codingblocks.com/s/152309

Will writing (temp1!=temp2) wouldn’t compare addresses.I thought of comparing the addresses because the data may be repeated. Sir, plz point out if it wrong to write(temp1!=temp2)

Hi @tanjuljain19,
The approach you undertook had some flaws. First our answer should be -1 if linked lists are not matching. Then since the linked lists are different. The address of the same valued node will be different, if it exists.
