You are provided with a positive integer N. Your goal is to determine the smallest number whose factorial has at least N trailing zeros.
N = 1
...
Find the smallest number whose factorial has at least N trailing zeros.
Calculate the number of 5's in the prime factorization of the factorial to determine the trailing zeros.
Use binary search to find the smallest number with at least N trailing zeros.
Consider edge cases like N = 0 or N = 1 for factorial trailing zeros problem.
Given three integers X
, Y
, and Z
, calculate the sum of all numbers that can be formed using the digits 3, 4, and 5. Each digit can be used up to a maximum of X
, Y
, and Z
t...
Calculate the sum of all numbers that can be formed using the digits 3, 4, and 5 with given constraints.
Iterate through all possible combinations of 3, 4, and 5 based on the given constraints.
Calculate the sum of each combination and add them up.
Return the final sum modulo 10^9 + 7.
Given a Weighted Directed Acyclic Graph (DAG) comprising 'N' nodes and 'E' directed edges, where nodes are numbered from 0 to N-1, and a source node 'Src'. ...
The task is to find the longest distances from a source node to all nodes in a weighted directed acyclic graph.
Implement a function that takes the number of nodes, edges, source node, and edge weights as input.
Use a topological sorting algorithm to traverse the graph and calculate the longest distances.
Return an array of integers where each element represents the longest distance from the source node to the corres...
Given an array arr
of size N
, determine the minimum number of swaps required to sort the array in ascending order. The array consists of distinct elements only...
The minimum number of swaps required to sort an array of distinct elements in ascending order.
Use a hashmap to store the index of each element in the array.
Iterate through the array and swap elements to their correct positions.
Count the number of swaps needed to sort the array.
You are given a N x M
matrix of integers. Your task is to return the spiral path of the matrix elements.
The first line contains an integer 'T' which denotes the num...
The task is to return the spiral path of elements in a given matrix.
Iterate through the matrix in a spiral path by keeping track of boundaries.
Print elements in the order of top row, right column, bottom row, and left column.
Continue the spiral path until all elements are printed.
Imagine you are Harshad Mehta's friend, and you have been given the stock prices of a particular company for the next 'N' days. You can perform up to two buy-and-sell t...
The task is to determine the maximum profit that can be achieved by performing up to two buy-and-sell transactions on a given set of stock prices.
Iterate through the array of stock prices to find the maximum profit that can be achieved by buying and selling stocks at different points.
Keep track of the maximum profit that can be achieved by considering all possible combinations of buy and sell transactions.
Ensure t...
You are playing a coin game with your friend Ninjax. There are N
coins placed in a straight line.
Here are the rules of the game:
1. Each coin has a value associated with...
The problem involves finding the optimal strategy to accumulate the maximum amount in a coin game with specific rules.
Start by considering the base cases where there are only 1 or 2 coins.
Use dynamic programming to keep track of the maximum amount that can be won at each step.
Consider the different scenarios when choosing a coin from either end of the line.
Keep track of the total winnings for both players and choo...
Determine if a given singly linked list of integers forms a cycle or not.
A cycle in a linked list occurs when a node's next
points back to a previous node in the l...
Detect if a singly linked list forms a cycle by checking if a node's next pointer points back to a previous node.
Traverse the linked list using two pointers, one moving one step at a time and the other moving two steps at a time.
If the two pointers meet at any point, there is a cycle in the linked list.
Use Floyd's Cycle Detection Algorithm for efficient detection of cycles in linked lists.
Virtual functions can be overridden in derived classes, while abstract classes cannot be instantiated directly.
Virtual functions are declared using the 'virtual' keyword and can be overridden in derived classes.
Abstract classes cannot be instantiated and may contain one or more pure virtual functions.
An abstract class can have virtual functions, but a virtual function does not make a class abstract.
