Polynomials python
Problem Statement :
poly The poly tool returns the coefficients of a polynomial with the given sequence of roots. print numpy.poly([-1, 1, 1, 10]) #Output : [ 1 -11 9 11 -10] roots The roots tool returns the roots of a polynomial with the given coefficients. print numpy.roots([1, 0, -1]) #Output : [-1. 1.] polyint The polyint tool returns an antiderivative (indefinite integral) of a polynomial. print numpy.polyint([1, 1, 1]) #Output : [ 0.33333333 0.5 1. 0. ] polyder The polyder tool returns the derivative of the specified order of a polynomial. print numpy.polyder([1, 1, 1, 1]) #Output : [3 2 1] polyval The polyval tool evaluates the polynomial at specific value. print numpy.polyval([1, -2, 0, 2], 4) #Output : 34 polyfit The polyfit tool fits a polynomial of a specified order to a set of data using a least-squares approach. print numpy.polyfit([0,1,-1, 2, -2], [0,1,1, 4, 4], 2) #Output : [ 1.00000000e+00 0.00000000e+00 -3.97205465e-16] The functions polyadd, polysub, polymul, and polydiv also handle proper addition, subtraction, multiplication, and division of polynomial coefficients, respectively. Task You are given the coefficients of a polynomial P. Your task is to find the value of P at point x. Input Format The first line contains the space separated value of the coefficients in P. The second line contains the value of x. Output Format Print the desired value.
Solution :
Solution in C :
import numpy
coefs=list(map(float,input().split()))
x=float(input())
print(numpy.polyval(coefs,x))

Merge two sorted linked lists
This challenge is part of a tutorial track by MyCodeSchool Given pointers to the heads of two sorted linked lists, merge them into a single, sorted linked list. Either head pointer may be null meaning that the corresponding list is empty. Example headA refers to 1 -> 3 -> 7 -> NULL headB refers to 1 -> 2 -> NULL The new list is 1 -> 1 -> 2 -> 3 -> 7 -> NULL. Function Description C

This challenge is part of a tutorial track by MyCodeSchool Given a pointer to the head of a linked list and a specific position, determine the data value at that position. Count backwards from the tail node. The tail is at postion 0, its parent is at 1 and so on. Example head refers to 3 -> 2 -> 1 -> 0 -> NULL positionFromTail = 2 Each of the data values matches its distance from the t

This challenge is part of a tutorial track by MyCodeSchool You are given the pointer to the head node of a sorted linked list, where the data in the nodes is in ascending order. Delete nodes and return a sorted list with each distinct value in the original list. The given head pointer may be null indicating that the list is empty. Example head refers to the first node in the list 1 -> 2 -
View Solution →Cycle Detection
A linked list is said to contain a cycle if any node is visited more than once while traversing the list. Given a pointer to the head of a linked list, determine if it contains a cycle. If it does, return 1. Otherwise, return 0. Example head refers 1 -> 2 -> 3 -> NUL The numbers shown are the node numbers, not their data values. There is no cycle in this list so return 0. head refer

This challenge is part of a tutorial track by MyCodeSchool Given pointers to the head nodes of 2 linked lists that merge together at some point, find the node where the two lists merge. The merge point is where both lists point to the same node, i.e. they reference the same memory location. It is guaranteed that the two head nodes will be different, and neither will be NULL. If the lists share
