EMC Hybrid Cloud Computing Interview Question and Answers

1) Given an input string and a dictionary of words, find out if the input string can be segmented into a space-separated sequence of dictionary words. Please ignore the case.

  d = ["emc", "great", "place", "is", "to", "work", "at", "ace", "tow"]
  s = "EMCIsGreatPlaceToWork"
  s = s.lower()
  segment = []
  while s:
      if s in d:
          segment.append(s)
          s = ""
      for i in range(1, len(s)):
          if s[:i] in d:
              segment.append(s[:i])
              s = s[i:]
              break
          if i == len(s)-1:
              s = ""
  print(segment)
  >>> ['emc', 'is', 'great', 'place', 'to', 'work']
  print(" ".join(segment))

  >>> emc is great place to work

2) write a program to sort the (name, age, score) tuples by ascending order where name is string, age and score are numbers. The tuples are input by console. The sort criteria is:
a) Sort based on name;
b) Then sort based on age;
c) Then sort by score.
The priority is that name > age > score.

If the following tuples are given as input to the program:
Tom,19,80
John,20,90
Jony,17,91
Jony,17,93
Json,21,85

Then, the output of the program should be:
[('John', '20', '90'), ('Jony', '17', '91'), ('Jony', '17', '93'), ('Json', '21', '85'), ('Tom', '19', '80')]

  from operator import itemgetter
  persons = []
  while True:
      line = input(">")
      if not line:
          break
      persons.append(tuple(line.split(",")))
  print(persons)
  >>> [('Tom', '19', '80'), ('John', '20', '90'), ('Jony', '17', '91'), ('Jony', '17', '93'), ('Json', '21', '85')]
  pesrsons = sorted(persons, key=itemgetter(0,1,2))
  print(persons)
  >>> [('John', '20', '90'), ('Jony', '17', '91'), ('Jony', '17', '93'), ('Json', '21', '85'), ('Tom', '19', '80')]

3) For the given string return 1 if it is a Palindrome else 0.

  def checkpalindrome():
      s = input("Enter the string:")
      if s == s[::-1]:
          return 1
      else:
          return 0
  checkpalindrome()

4) For the given string remove the white spaces.

  s = "EMC is great place to work"
  s = s.split()
  s = "".join(s)
  print(s)
  >>> EMCisgreatplacetowork
