First, solve the original puzzle:
- If Harsha is truth-teller -> exactly one liar -> p2 and p3 are truth-tellers.
Then p2 (truth) says 'Harsha and Leena same type' - true (both truth) - consistent.
p3 (truth) says 'at least one truth-teller' - true - consistent.
Solution: Harsha=T, Deepa=T, Leena=L

Now, hypothetically assume Harsha is liar instead of truth-teller.
Then we need to re-solve:
- Harsha liar -> statement 1 false -> number of liars is NOT exactly one -> 0, 2, or 3 liars.
- If 0 liars, all truth-tellers. Then Harsha truth - contradicts Harsha liar.
- If 2 liars, then Deepa and Leena are liars. Then Deepa liar says 'Harsha and Leena same type' - Harsha liar, Leena liar -> same type -> true statement, but liar can't make true - contradiction.
- If 3 liars, all are liars. Then Deepa liar says 'Harsha and Leena same type' - both liars -> same -> true statement - contradiction.
- Therefore, no consistent assignment exists when Harsha is liar.
