Epic的OA最近火热发放这,包含多种题型,限时3个小时,这里CSoahelp给大家分享一下部分的真题

1: Broken Labeler
You need to label a large number of files from 1 to N, but one number key on your labeler is broken. Write a program that prompts the user for N and the broken number key, then prints the highest possible file number the user can print on the labeler. For example, if the user enters N=56781232 and the broken number key is 2, then the highest possible file number is 56781199.

2: Cheaters
There are two places to enter a raffle contest. People enter the raffle contest by writing their seven-digit phone numbers on a slip of paper and turning them in at one of the two places. Some people try to beat the odds and enter at both places. They are considered cheaters and should have both of their entries removed. The two raffle locations have each generated a sorted array of phone numbers turned in at their respective locations. Your function will take these arrays as input and print a combined and sorted list of phone numbers that eliminates duplicate entries.

3: Mingo
The game of Mingo involves a 100 x 100 board with unique positive whole numbers in the range from 1 to 1,000,000 randomly distributed in the cells. Unique numbers are "called" one at a time and the goal is to have a "Mingo," which is an entire row or column of cells with numbers that have been called; one might also form a diagonal from corner to corner with numbers that have been called. Write a function that takes as parameters a square array of 100 x 100 positive whole numbers and a list of "called" numbers. Your function will report whether a "Mingo" occurs, and after how many called numbers the first Mingo occurs. You may assume valid input.

4: Phone Numbers
A company is choosing phone numbers for its employees. In order to avoid confusion, the company has decided that no phone number will contain the same digit more than once in a row (so 0232 is allowed, but not 0223 or 0222). Additionally, any phone number that contains a 4 must begin with 4. The company has also decided to exclude up to three additional digits from the number, but it hasn’t decided which ones yet. Write a function that takes the length of the phone number and the additional digits to be disallowed in the number as parameters and prints all possible valid phone numbers. You may assume valid input.

5: Cash
One week ago we had $50,000 in the checking account and $550 in cash. Since then, the following transactions took place:

  • We bought 200 $0.44 postage stamps and paid with cash.
  • We bought 2 computers for $2,100 each. We paid 1/12 of this with cash and 1/6 with a check.
    (Please disregard the remaining balance for purposes of this problem.)
  • We paid 5 employees their weekly salary (based on a 52-week year) by check. Each employee earns $26,000 per year.

What is the total left in cash?

7: Missing Number in Sequence
What is the missing number in the following sequence?
3 8 18 __ 78 158

12: Fruit Cost
Under certain circumstances, an apple costs 10 cents, a banana costs 15 cents, and a grapefruit costs 20 cents. How much will a pear cost under the same circumstances?

14: Rectangular Bin
A rectangular bin holds 300 cubic feet of sand. If the bin is 10 feet long and 10 feet wide, how deep is it?
