- There are three financial aid counselors. If a student’s last initial is from A – H, let them know that their counselor is Jon Stewart. If a student’s last initial is from I – Q, let them know that their counselor is Chelsea Handler. If a student’s last initial is from R – Z, let them know that their counselor is Brian Williams.Ask student for the FICO score, if it’s less than 660 tell that this student cannot have a loan. c++arrow_forwardThere are 22 gloves in a drawer: 5 pairs of red gloves, 4 pairs of yellow, and 2 pairs of green. You select the gloves in the dark and can check them only after a selection has been made. What is the smallest number of gloves you need to select to have at least one matching pair in the best case? in the worst case?arrow_forwardSabrina is on a game show and is presented with a drawer containing 10 red socks, 10 blue socks, 10 green socks, and 10 yellow socks. Sabrina is to take socks out of the drawer and put them in a bag. She will win 1ドル for every sock she puts in the bag, as long as the bag does not contain 5 or more socks of one color and 5 or more socks of another color. For example, if she takes 5 red, 4 blue, 3 green, and 2 yellow socks, she would win 14ドル. However, if she took 5 red, 5 blue, 3 green, and 2 yellow socks, she would not win anything because there are two colors (red and blue) that have 5 or more socks each. What is the most money that Sabrina can win? Enter your answer as a single integer only (no words, no dollar signs). A/ What is the minimum number n such that if n socks are removed from the drawer and put into a bag, that the bag will necessarily contain at least 5 socks of one color and at least 5 socks of another color? Enter n as a single integer, no words.arrow_forward

- Determine the value of the decision parameter for the circle drawing technique described by Bresenham on page. Bresenham's method for drawing circles is shown here in a stage-by-stage format.arrow_forwardX-Kingdom has trapped n number of soldiers of their opponent. They want to execute them. They created a strategy so that the prisoners will kill each other and at the end one prisoner will be alive and eventually released. As part of the process, they assigned each trapped soldier a sequence number starting from 1 and ending at n. If n = 5 and k = 2, then the safe position is 3. Firstly, the person at position 2 is killed, then person at position 4 is killed, then person at position 1 is killed. Finally, the person at position 5 is killed. So, the person at position 3 survives. If n = 7 and k = 3, then the safe position is 4. The people at positions 3, 6, 2, 7, 5, 1 are killed in order, and the person at position 4 survives. Input:n and k Output:Print the list of prisoners in reverse order from n to 1Then reverse the list to print it in correct order from 1 to nDisplay the position number who will survive. You must have to use circular doubly linked list for your solution.
