Bank of America计算机科学面试真题

You are given a number N and a pattern. The pattern consists of lowercase Latin letters and one operation '+' or '-'. The challenge is to split the number and evaluate it according to this pattern e.g., 1252 ab+cd → a:1, b:2, c:3, d:2 → 12+32 → 44. Your program should read lines from standard input. Each line contains the number and the pattern separated by a single whitespace. The number will be in range [100, 1000000000]. All test cases contain valid expressions (no leading zeros).

Write a program that, given an integer N, sums all the whole numbers from 1 through N (both inclusive). Do not include in your sum any of the intermediate values (1 and N inclusive) that are divisible by 5 or 7. Your program should read lines from standard input. Each line contains a positive integer. For each line of input, print to standard output the sum of the integers from 1 through n, disregarding those divisible by 5 and 7. Print out each result on a new line.

What languages have you used before? What projects have you worked on? Can you describe a situation where you had to ensure that the code you wrote would not be broken by the next person who works on it?
