Print All Distinct Elements of a given integer array in C++
In this problem, we are given an array of integer values. Our task is to print all distinct elements of the array. The output should contain only distinct values.Let’s take an example to understand the problemInput: array = {1, 5, 7, 12, 1, 6, 10, 7, 5} Output: 1 5 7 12 6 10To solve this problem, we will have to check elements of the array for uniqueness. For this, we will use two nested loops, the outer one will take values and the inner one will check the rest of the values with it. If more than one values ...
Read MoreRotate String in Python
Suppose we have two strings, A and B. We will rotate the string A and check whether it matches with B at any position of rotating, if so then return true, otherwise false. For example, if A = 'abcde', and B = 'bcdea' So answer will be true, as A can be converted to B after rotating it.To solve this, we will follow these steps −When both A and B are empty, then return true, when both are of different length then return falseA := concatenate A after Ai := 0, and j := 0while i < length of Aif ...
Read MoreFind N integers with given difference between product and sum in C++
Suppose we have two integers N and D. We have to find a set of N integers, where the difference between their sum and product is the same as D. Suppose the N = 3, and D = 5, then the output will be 1, 2, 8. Here the sum is 1 + 2 + 8 = 11, and product is 1 * 2 * 8 = 16, the difference between 16 and 11 is 5.We have to solve this problem; we will use one tricky method. Here we will try to find N–2 number of 1s, one 2, and ...
Read MorePrint all distinct circular strings of length M in lexicographical order in C++
In this problem, we are given a string and an integer M. our task is to print all distinct circular strings of length M in lexicographical order (alphabetical order).Let’s take an example to understand the problem, Input: str= “ssssn” M=3 Output: nss sns ssn sssExplanation − all possible circular strings of length 3 are: sss sss ssn sns nss. Distinct elements in lexicographical order are sss ssn sns nss.To solve this problem, we will iterate over the elements of the string and generate all possible substrings of length M. we will store this generated string in a set that stores ...
Read MoreFind n-th element from Stern's Diatomic Series in C++
Here we will see how to find the nth term in Stern’s Diatomic series. The series is like 0, 1, 1, 2, 1, 3, 2, 3, 1, 4, 3, 5, 2, 5, 3, 4, … This is also known as fusc function. This series can be defined as −𝑝(𝑛)=$p\lgroup\frac{n}{2}\rgroup$ 𝑤ℎ𝑒𝑛 𝑛 𝑖𝑠 𝑒𝑣𝑒𝑛𝑝(𝑛)=$p\lgroup\frac{n-1}{2}\rgroup+p\lgroup\frac{n+1}{2}\rgroup$ 𝑤ℎ𝑒𝑛 𝑛 𝑖𝑠 𝑜𝑑𝑑𝑝(0)=0 𝑎𝑛𝑑 𝑝(1)=1Here we will use the Dynamic programming approach to reduce the number of computations. After saving the base case for p(0) and p(1), we will iterate from index i = 2 to n, and compute p(i)Example#include using namespace std; int findTerm(int n) ...
Read MoreGoat 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 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 MorePrint all distinct characters of a string in order in C++
In this problem, we are given a string. Our task is to print all distinct characters of the string in the order they appear in the string.Let’s take an example to understand our problem, Input: tutorials Point Output: uralsPnThere are multiple ways to solve this problem but we will discuss the most effective one. The simple one includes the nesting of loops.For this, we will use two arrays of size 256(8-bit characters are stored).First we will initialize all values of counter array to 0 and all values of index array to n (length of string). On traversal of the string ...
Read MoreProgram to print a rectangle pattern in C++
In this tutorial, we will be discussing a program to print a given rectangular pattern.For this we will be given with the height and the breath of the rectangle. Our task is to print the rectangle with the given dimensions using the “@” character.Example#include using namespace std; void print_rec(int h, int w){ for (int i=0; i
Read MoreReverse Only Letters in Python
Suppose we have a string S, we have to find the reversed string where all characters that are not a letter will not change their positions and all letters reverse their positions. So if the given string is "a-bC-dEf-ghIj", then output will be "j-Ih-gfE-dCba"To solve this, we will follow these steps −We will use the regular expression library to solve thisif S is empty, then return Sstr := an empty string, index1 := 0 and index2 := length of S – 1while index1 < length of Sif index2 >= 0 and S[index1] is alphabet and S[index2] is alphabetstr := str ...
