It's time to thank all the professors at IITK who guided us through the 4 years of the best period of our life. Saurav and I decided to meet all the professors who taught us at IITK. Most of the professors were surprised that we had come, as it was unusual that any graduating student would have come to wish adieu. We were flooded with their blessings and kind advises. Later, Anadi helped me to extend this list.
