User IDs on a website consist of four lowercase letters (a–z) followed by one digit (0–9). An example would be abcd1. Determine thenumber of user IDs possible if: (a) the first letter must beq, the digit must be less than4, andrepetition is permitted. (b) the letters must not be vowels (a, e, i, o, u), the number must be even, and repetition is not permitted.

A Web site validates a 16-digit ID number based on the following rules - 1. Starting with the leftmost digit, double it and then double every other digit after it. However, if any of the doubled digits is a two-digit number, subtract 9 from it. Then sum these new digits. For instance, if the ID card number is 5866793610024475, then the digits considered are 5, 6, 7, 3, 1, 0, 4, 7, their new replacements are 1, 3, 5, 6, 2, 0, 8, 5 and the sum of the replacement is 30. 1 2 3 4 6. 7 8 9 10 11 12 13 14 15 8. 6. 7 9 3 6 1 4 4 7 5 6 7 1 4 7 5*2-9 6*2-9 7*2-9 3*2 1*2 0*2 4*2 7*2-9 =1 =3 =5 =6 =2 =0 =8 =5 2. Sum together the remaining sever digits from the ID card number. That is, the digits in the odd-numbered positions. With the ID card number above, we obtain 8+6+9+6+0+2+4+5 = 40. 3. Add together the two sums. If the result is a multiple of 10, then accept the ID card number. Otherwise, reject it. We accept the ID card number since 30+40=70, a multiple of 10.

Computer Science Many websites let users rate items by selecting some number of stars. On the web, this is usually implemented with a small Javascript program that runs in the browser. In any state, a sequence of stars is displayed, with a (possibly empty) prefix in a distinct color, representing the current selection. The user can extend and contract the prefix simply by hovering over the displayed stars. When the user clicks on a star, the current selection is submitted, and the browser issues an HTTP POST request to the server. The selection may start showing no stars (that is, the empty prefix), or it may already show one star or more. To allow the user to reset to no stars, a click on the final star in the previous submission is treated as a reset. Model this mechanism as a transition system. You should start by designating events; you may need to refine your designations as you think more carefully about the problem. You should include, in addition to the user inputs, the outputs…

Problem Description MyKad is the compulsory identity card for Malaysian citizens aged 12 and above. The current format of the Malaysian identity card number was introduced in 1990, features 12 digits separated into three blocks by hyphens, as illustrated below: YYMMDD-PB-###G The first six digits signify the person's date of birth in the ISO 8601:2000 format; the seventh and eighth digit, represents the place of birth of the person. The ninth through eleventh digit is the generic special number generated by the National Registration Department of Malaysia's computer system. G, the 12th digit represents the gender of the person. The odd number for G denote male while the even number denote female. For example, 2906 is female (6 is even number) and 8995 is male (5 is odd number) You are given a list of the last 4 digits of MyKad. Write a program to calculate the number of male and female. Input The input starts with X (1M F Sample Input Output Sample Input 5 2906 2652 8195 3441 9534…
