Write python code for the following
Implement a method Boolean containPattern(String s) to find the following special pattern in String s:
Sequence1&Sequence2
Where
- Sequence 1 and Sequence 2 do not contain symbol ‘&’
- Sequence 2 should be the reversed version of Sequence 1
e.g.
input: a+b&b+a
output: true
input: 1+3&3-1
output: false
Homework Answers
def containPattern(s): sequences = s.split('&') if len(sequences) == 2: s1 = sequences[0] s2 = sequences[1] reverse = '' for ch in s1: reverse = ch + reverse return s2 == reverse return False print(containPattern('a+b&b+a')) print(containPattern('1+3&3-1'))
def containPattern(s):
sequences = s.split('&')
if len(sequences) == 2:
s1 = sequences[0]
s2 = sequences[1]
reverse = ''
for ch in s1:
reverse = ch + reverse
return s2 == reverse
return False
print(containPattern('a+b&b+a'))
print(containPattern('1+3&3-1'))

Write Java code to implement a FSM machine that recognizes the language for the alphabet {a,b,c} consisting of all strings that contain two consecutive c's and end with b. Your FSM program should include the following three static methods (Java) or functions (C): a. int nextState(int state, char symbol) A state-transition function that returns the next state based on the current state and an input symbol. This function should also return -1 when an invalid input character is detected. State...

using c language String Challenge Have the function StringChallenge(str) read str which will contain two strings separated by a space. The first string will consist of the following sets of characters: +, *, $, and {N} which is optional. The plus (+) character represents a single alphabetic character, the ($) character represents a number between 1-9, and the asterisk (*) represents a sequence of the same character of length 3 unless it is followed by {N} which represents how many...

def findSubstrings(s):
# Write your code here
Consider a string, s = "abc". An alphabetically-ordered sequence of substrings of s would be {"a", "ab", "abc", "b", "bc", "c"}. If the sequence is reduced to only those substrings that start with a vowel and end with a consonant, the result is {"ab", "abc"}. The alphabetically first element in this reduced list is "ab", and the alphabetically last element is "abc". As a reminder: • Vowels: a, e, i,...

Java question
Write the method reversed that returns true if and only if the arrays a and b contain exactly the same elements, but in reversed order. For example, reversed ({3, 1}, {1, 3}) returns true, but reversed ({3, 1}, {2, 3}) and reversed ({3, 1}, {1, 1, 3}) both return false. public static boolean reversed (int [] a, int [] b) should return true if and only if a and b contain the same elements, reversed.
