C++ code to count number of times stones can be given
Suppose we have a number n. Amal gives some stones to Bimal and he gives stones more than once, but in one move if Amal gives k stones, in the next move he cannot give k stones, so given stones in one move must be different than the previous move. We have to count the number of times Amal can give stones to Bimal.So, if the input is like n = 4, then the output will be 3, because 1 stone then 2 stones then again 1 stones.StepsTo solve this, we will follow these steps −return (n * 2 + ...
Read MoreC++ code to find how long person will alive between presses
Suppose we have four numbers d, L, v1 and v2. Two presses are initially at location 0 and L, they are moving towards each other with speed v1 and v2 each. The width of a person is d, he dies if the gap between two presses is less than d. We have to find how long the person will stay alive.So, if the input is like d = 1; L = 9; v1 = 1; v2 = 2;, then the output will be 2.6667StepsTo solve this, we will follow these steps −e := (L - d)/(v1 + v2) return eExampleLet ...
Read MoreC++ code to find minimum jump to reach home by frog
Suppose we have one binary string S with n bits and another number d. On a number line, a frog wants to reach point n, starting from the point 1. The frog can jump to the right at a distance not more than d. For each point from 1 to n if there is a lily flower it is marked as 1, and 0 if not. The frog can jump only in points with a lilies. We have to find the minimal number of jumps that the frog needs to reach n. If not possible, return -1.So, if the input ...
Read MoreC++ code to count maximum groups can be made
Suppose we have an array A with n elements. There were n groups of students. A group is either one person who can write the code with anyone else, or two people who want to write the code in the same team. But the mentor decided to form teams of exactly three people. We have to find the maximum number of teams of three people the mentor can form. For groups of two, either both students should write the code, or both should not. If two students from a group of two will write the code, they should be in ...
Read MoreJava Program to Convert the LinkedList into an Array and vice versa
In this article, we will understand how to convert the linked list into an array and vice versa. The java.util.LinkedList class operations perform we can expect for a doubly-linked list. Operations that index into the list will traverse the list from the beginning or the end, whichever is closer to the specified index.Below is a demonstration of the same −Suppose our input is −The list is defined as: [Java, Python, Scala, Mysql]The desired output would be −The result array is: Java Python Scala MysqlAlgorithmStep 1 - START Step 2 - Declare namely Step 3 - Define the values. Step 4 ...
Read MoreJava Program to Print Boundary Elements of a Matrix
In this article, we will understand how to print boundary elements of a matrix. A matrix is representation of the elements in rows and columns. Boundary elements are those elements which are not surrounded by elements on all four directions. For example, the elements in the first row, first column, last row and last column.Below is a demonstration of the same −Suppose our input is −The input matrix: 9 8 9 8 8 7 8 7 7 6 7 6 6 5 6 5The desired output would be −The border elements of the matrix is: 9 8 9 8 8 ...
Read MoreJava Program to Replace the Spaces of a String with a Specific Character
In this article, we will understand how to replace the spaces of a string with a specific character. String is a datatype that contains one or more characters and is enclosed in double quotes(“ ”).Below is a demonstration of the same −Suppose our input is −Input string: Java Program is fun to learn Input character: $The desired output would be −The string after replacing spaces with given character is: Java$Program$is$fun$to$learnAlgorithmStep 1 - START Step 2 - Declare a string namely input_string, a char namely input_character. Step 3 - Define the values. Step 4 - Using the function replace(), replace the ...
Read MoreJava Program to Remove a Sublist from a List
In this article, we will understand how to remove a sub-list from a list. A list is an ordered collection that allows us to store and access elements sequentially. It contains the index-based methods to insert, update, delete and search the elements. It can also have the duplicate elements.Below is a demonstration of the same −Suppose our input is −Input list: [Java, Programming, Is, Fun]The desired output would be −The list after removing a sublist is: [Java, Programming]AlgorithmStep 1 - START Step 2 - Declare an AbstractList namely input_list. Step 3 - Add the values to the list. Step 4 ...
Read MoreC++ code to count days to complete reading book
Suppose we have an array A with n elements and have another value t. On ith day Amal spends A[i] seconds in work. In the free time he reads a book. The entire book will take t seconds to complete. We have to find how many days he will need to read the complete book.So, if the input is like A = [86400, 86398]; t = 2, then the output will be 2, because one day has 86400 seconds, and first day is totally blocked. On second day he will get 2 seconds to complete the book.StepsTo solve this, we ...
Read MoreJava Program to Create random strings
In this article, we will understand how to create random strings. String is a datatype that contains one or more characters and is enclosed in double quotes(“ ”).Below is a demonstration of the same −Suppose our input is −The size of the string is defined as: 10The desired output would be −Random string: ink1n1dodvAlgorithmStep 1 - START Step 2 - Declare an integer namely string_size, a string namely alpha_numeric and an object of StringBuilder namely string_builder. Step 3 - Define the values. Step 4 - Iterate for 10 times usinf a for-loop, generate a random value using the function Math.random() ...
