Based on the participant feedbacks, we revisited all the questions again. Taking into consideration the opinion from our internal team members, we've finally decided to bulk re-evaluate 4 problems from Slot-1:

Colourful algorithmic journey (Action: Language in one of the cases was ambigious and mayn't have proper clarity. Full points provided to all, irrespective of attempted or not)

The Goblin's Gamble (Action: Both options - 'Only accept if both dice show 1 or 6' and 'Bluff the goblin with deception' are correct depending upon the situation and any one will yield full points)

Toyville problem (Action: Both options - Apart from '1 toy', 'Buying no toys' may be also considered correct, taking real-life scenario and any one will yield full points)

Race problem (Action: Both 'E' and 'B' may've finished the race first due to lack of information and any one will yield full points)

One or two queries were received on the 'feathered adventure (100 birds)' and 'conversation on numbers between 2 friends' problems. Both are perfectly fine and no changes need to be applied.
