Largest number in [2, 3, .. n] which is co-prime with numbers in [2, 3, .. m]
Co-prime numbers are numbers that do not have any common divisor other than 1. We will be given two numbers n and m. We have to find the largest number in the range of 2 to n (both inclusive) which is co-prime with all the elements in the range of 2 to m (both inclusive). If none of the elements in the given range is co-prime with all the elements of the second range then we have to return or print -1. We will implement the approach, and code, and will discuss the time and space complexity of the program. ...
Read MoreP – smooth numbers in given ranges
P smooth numbers are the numbers that have the maximum prime number that can divide them is less than or equal to the given number P. Prime numbers are the numbers that are divisible by only 1 and that number. 1 is by default considered as the P - smooth number for any given value of P. In this problem, we will be given a value P and the range and we have to return the number of elements that are present in that range and are P-smooth. Input Given the value of P is 7 and the range ...
Read MoreHow to validate ISIN using Regular Expressions?
In this problem, we will use the regular expression to validate the ISIN number in C++. The ISIN stands for the International Securities Identification Number. It is a unique code to identify stocks, financial bonds, etc. The length of the ISIN number can be 12 or 14, which provides international recognization of the particular stuff. Let’s understand the format of the ISIN number. Country code − It starts with two characters of the country code. Identifier − It contains 9 alphanumeric characters after the country code. Checksum − It contains the single digit which is used to detect errors ...
Read MoreFind the final String by incrementing prefixes of given length
In this problem, we need to increase each character of multiple prefixes of size given in the array. The naïve approach to solving the problem is to take each prefix of the size given in the array and increment each character of the prefix by 1. The best approach is to create the prefix array using the given array and update each string character in the single iteration. Problem statement − We have given a string alpha of length N. Also, we have given a prefixes array containing the positive integer. The prefixes[i] represent that take prefix of length prefixes[i] ...
Read MoreC++ Program to Implement Stack using array
A stack is an abstract data structure that contains a collection of elements. Stack implements the LIFO mechanism i.e. the element that is pushed at the end is popped out first. Some of the principle operations in the stack are −Push - This adds a data value to the top of the stack.Pop - This removes the data value on top of the stackPeek - This returns the top data value of the stackA program that implements a stack using array is given as follows.Example#include using namespace std; int stack[100], n=100, top=-1; void push(int val) { if(top>=n-1) ...
