### Code

```import math

def binomialCoefficient(n, k):
if n < k:
return 0
return factorial(n) / (factorial(k) * (factorial(n - k)))

def factorial(n):
if n == 0:
return 1

result = 1
for i in range(1, n + 1):
result *= i

return result

input = input()
if len(input) == 0:
print (0)
sys.exit()

subsets = 0
for i in range(ord('A'), ord('Z') + 1):
letterCount = input.count(chr(i))
subsets += (binomialCoefficient(letterCount, 2) + letterCount)

print (math.floor(subsets))```
