Question

https://code.sololearn.com/cigzSSTzyOAK/?ref=app

the program runs nicely until I give the input Password12#$, the expected output for the given input is 'Strong' but my output is 'Weak' I don't know why please help me

Answer 1

Password12#$
012345678901

length is 12
$ is 11

for(int i=0; i < password.length-1; ++i)
11 < 12 - 1
11 < 11 false
last char in pasword is ignored

Answer 2

for loop is not iterating complete list.
correct length in both for loops as below.

i<password.length
a<password.length

Note: Try to avoid number of "for loops" to reduce the time complexity of the code.
