5. check if n is a power of 10
6. Replace all even digits with an odd number 1 greater than it (next)
7. remove the odd digits from n
8. check that the number has all the digits equal
9. Displays the largest number that can be formed with the distinct digits that it has
contains n (eg for n = 25330727, 75320 will be obtained)

i would first let him be aware that a cover letter is official and confidential and it requires a proper formatting so that the employer doesn't have hard time when going through it. he should write it in paragraphs of about two to four sentences and use proper grammar a , spelling and proper punctuation. i will also advice him not to be emotional and not also to use images.then base his attention to the details of the job described and not other things. that is he be specific to the responsibilities and to the employers requirements. on this he should make sure that the letter reflects how good he is for the requirements detailed by the employer

the letter should not be too long nor too short.
