# Write a python program that will take N as input from the user and then take N lines of input from the user. Each line will contain a tennis player name, year and tournament name that he won that year. Store each player's championship information in a dictionary where the key will be the player name and corresponding value will be a list containing all the tournaments the player won along with the year of the tournament. 
# Sample Input 1:
# 6
# ztm-zdas-und
# 2021 FrenchOpen Djokovic
# 2020 FrenchOpen Nadal
# 2020 USOpen Dominic
# 2020 AustralianOpen Djokovic
# 2019 USOpen Nadal
# Sample Output 1 (No need to follow this output format. Just print the resultant dictionary. ):
# {'Djokovic': {2021:['AustralianOpen','FrenchOpen'], 2020:['AustralianOpen']}, 'Nadal': {2020:['FrenchOpen'], 2019: ['USOpen']}, 'Dominic': {2020:['USOpen']}}
