plz help i don t understand this at all background google entices job searchers with 5187460


Background: Google Entices Job-Searchers with Math Puzzle. Lets see whether we can solve the puzzle with MatLab Mysterious banners at a Cambridge, Mass, subway stop have commuters scratching their heads. The signs, challenging passers-by to solve a complicated math problem, are actually a cryptic pitch by Google, which is looking to hine more brainy engineers. More information can be found here: http/www.npr.org/templates/story/story php?storyld 3916173 Problem: Findd the frst 10-digit prime found in consecutive digits of e How: I saved the first 2 million digits of e into a file named e.txt. You can download the flie from Moodle, and save it into the directory where MatLab can find (You home directory under Linux, or Documents/MATLAB directory under windowa). You can write a program. The program reads the digits into a string and scans the string to find prime numbers. Every time, the program gets 10 characters (since the problem is to find 10-digit prime number), translates the characters into a number, and checks whether the number is prime number or not (call isprime) function). So, the framework is as folows: %read file and save the digts into a string strahcantnd. %s); %search a 10-digit prime number for index-1:lengthistr)- substr strindecindex+) num-str2doublel(substr) % check whether the rumber is 10-digit (some numbers like 0000123456 are not 10 digit. and check whether the number t numo... Iisprimelnum). prne end
