Anagram solver in python Two strings are anagrams if they contain the same set of characters regardless of the order of individual characters such as “earth” and “heart”. Write python code to detect if two strings are anagrams. Python anagram solver code Here is the code in python. You may also check this solution in
Python repeated character in string Given a string of characters. Write python code to print the repeated characters Solution This is a typical dictionary based problem. Here is how to do that in Python. You may need to take a look at the following similar articles Character count in string java String repeated characters count
LZW Algorithm: Introduction It is beyond our imagination to specify a ceiling for the amount of information that an individual or a group of people potentially need to store and/or exchange. Using computer systems, almost all kinds of information can be digitized and therefore saved to storage media or sent across channels all over the
Problem Provide example code in Perl to implement an array of C like structs Solution Use a hash table. The hash key is recommended to be a unique identifier and the hash value is a reference to an array. The idea is simple and the rest is just using the correct Perl syntax Code Here
Problem You have a log file on UNIX operating system. Each line in the log file contains an IP address in the 10th column where columns (or fields) are separated by a space. Write a Perl program to parse the log file and print the unique IP addresses in the log file Solution Read the
Problem Given an array of n-1 unique integers. Each element in the array is an integer between 1 and n. Write a program to print the missing number in the array Solution To clarify this problem let us take a simple example. Assume n = 3 so the array consists from two elements only. Here
Problem Given a log file similar to Linux syslog format as in the following example: Write a Perl script to print the top 5 most repeated error messages. Solution Read the file line by line then split each line using “:” as separator then use the error message token as the key in a hash
Most repeated character string Given a string of characters find the character that is repeated the most. Solution This is almost the same as the First None Repeating Char problem. We are going to borrow the same code however we will slightly modify it. The only code that we need to add is calculating the
Problem Write code to simulate the SQL statement “Select unique emp_name from employees” Solution Assuming we have an array of employee names we need to write a function that prints the unique employee names in the array. We can use a built in hash table for that matter. Just hash all names then print the
Problem Write a Java program to find character counts in a string consisting from capital letters (A to Z) only. The program must not use nested loops. Hash tables that are built in to the language must not be used as well. For example if the input string is “CACBACDDDD” the output of the program
