Goat Latin in Python
Suppose we have a set of strings (Sentence), in that set there are few words. Each words are consists of lowercase and uppercase letters. Our task is to convert the sentence into Goat-Latin form. The Goat Latin is similar to the Pig Latin. There are some few conditions.If the word starts with a vowel, then append ‘ma’ with the wordIt the word starts with a consonant, then remove that from beginning, and append it at the end, then add ‘ma’ at the end.Add one letter ‘a’ to the end of each word per its word index in the sentence, starting ...
Read MorePrint all subarrays with 0 sum in C++
In this problem, we are given an array of integer values and we have to print all those subarrays from this array that have the sum equal to 0.Let’s take an example to understand the topic better, Input: array = [-5, 0, 2, 3, -3, 4, -1] Output: Subarray with sum 0 is from 1 to 4. Subarray with sum 0 is from 5 to 7 Subarray with sum 0 is from 0 to 7To solve this problem, we will check all subarrays possible. And check if the sum of these subarrays is equal to 0 and print them. This ...
Read MorePrint all subsequences of a string using Iterative Method in C++
In this problem, we are given a string and we have to find the substring from the given string. The substring to be found should start with a vowel and end with constant character.A string is an array of characters.The substring that is to be generated in this problem can be generated by deleting some characters of the string. And without changing the order of the string.Input: ‘abc’ Output: ab, ac, abcTo solve this problem, we will iterate the string and fix vowels and check for the next sequence. Let’s see an algorithm to find a solution −AlgorithmStep 1: Iterate ...
Read MoreFair Candy Swap in Python
Suppose A and B are two friends. They have candy bars of different sizes. Here A[i] is the size of the i-th bar of candy owned by A, and B[j] is the size of the j-th bar of candy owned by B.Since they are friends, they want to exchange one candy bar each so that after the exchange, both A and B have the same total amount of candy. (The total amount of candy a person has is the sum of the sizes of candy bars they have.) We have to return an integer array suppose ans, where ans[0] is ...
Read MoreAdd to Array-Form of Integer in Python
Suppose we have a number in array form. So if the number is say 534, then it is stored like [5, 3, 4]. We have to add another value k with the array form of the number. So the final number will be another array of digits.To solve this, we will follow these steps −Take each number and make them string, then concatenate the stringconvert the string into integer, then add the numberThen convert it into string again, and make an array by taking each digit form the string.ExampleLet us see the following implementation to get better understanding −class Solution(object): ...

Read MorePrint all paths from a given source to a destination in C++
In this problem we are given a directed graph and we have to print all paths from the source to the destination of the graph.Directed graph is a graph in with edges that are directed from vertex a to b.Let’s take an example to understand the problem Source = K destination = POutput:K -> T -> Y -> A -> P K -> T -> Y -> P K -> A -> PHere, we have found paths from K to P. We have traversed paths and printed all paths from K that direct us to P.To solve this problem, we will ...
Read MoreHello World using Perl.
Perl is a programming language developed by Larry Wall, specially designed for text processing.Just to give you a little excitement about Perl, I'm going to give you a small conventional Perl Hello World program,You can try it using the Demo link.Example#!/usr/bin/perl # This will print "Hello, World" print "Hello, world";
Read MoreEscaping Characters in Perl
Perl uses the backslash (\) character to escape any type of character that might interfere with our code. Let's take one example where we want to print double quote and $ sign −Example#!/usr/bin/perl $result = "This is "number""; print "$result"; print "\$result";OutputThis will produce the following result −This is "number" $result
Read MoreAccessing Hash Elements in Perl
When accessing individual elements from a hash in Perl, you must prefix the variable with a dollar sign ($) and then append the element key within curly brackets after the name of the variable. For example −Example#!/usr/bin/perl %data = ('John Paul' => 45, 'Lisa' => 30, 'Kumar' => 40); print "$data{'John Paul'}"; print "$data{'Lisa'}"; print "$data{'Kumar'}";OutputThis will produce the following result −45 30 40
