Problem Statement:
It’s very simple, we need to find the number of strings equal to each other, and that’s it. This was the technical intro to the problem. Now, let’s see the actual problem. We are given some names and we need to find the number of pairs that exist. A pair means two names are equal to each other.
Code to find Names and Nicknames in Python:
t = int(input('Enter number of test cases: '))
for i in range(t):
n = int(input('\nEnter number of people: '))
names = []
for j in range(n):
names.append(input('Enter new name: '))
count_ = []
for i in names:
count_.append(names.count(i))
if max(count_)>1:
print('Yes, there is 1 or more pair(s) exist')
else:
print('No pair exist')Output:
