### Code

```def calculateWrongPartitions(s):
substraction = 0
a, b = s[0 : len(s) -1], s[1 : len(s)]

if(not len(a)==len(set(a))):
substraction += 1 + calculateWrongPartitions(a)
if(not len(b) == len(set(b))):
substraction += 1 + calculateWrongPartitions(b)

return substraction

def main():
s = input()

partitions = pow(2, len(s)-1) - 1
partitions -= calculateWrongPartitions(s)

print(partitions%(pow(10, 9)+7))

if(__name__ == '__main__'):
main()
```
