You receive capcha submissions from users (or bots?) and you need to count how many wrong aswers have been submitted (potential bots).

Each submission consists of catcha string and the answer. Captcha hides a simple mathematical expression with some addtional noise that can be any small or capital letter of the alphabet, examples: "AbC3rr-HH2jj", GGG9*5

For example, when the function countBots(submissions) is invoked with the following array of submissions:

[
  {
    captcha:"1+1", 
    answer: 2,
  },
  {
    captcha:"abc5*ab2a", 
    answer: 2,
  }
]

it should return 1, becasue one of the submissions has wrong answer (5x2=10 not 2)
