Q1.What is the smallest 32-bit floating point number f such that 128 + f > 128 ? What is the smallest 32-bit floating point number g such that 1 + g > 1 ? What is the relationship between f and g? Where f and g are differentiable functions. We have found that the given functions have the same derivative. In general, if two differentiable functions differs by a constant at x, its derivatives slopes at this point are the same. Write a short C++ or Python program to support your answer (for example, show that you checked whether there is no smaller number than your f by trying 128+f/2 == 128. Q2.

You are given a sequence of integers A1, A2,..., AN and an integer M. For any valid integers p, q, let's define F(p,q) as the dot product of the subsequences Ap, Ap+1, . .., Ap+M–1 and Aq, Aq+1, . .., Aq+M–1, İ.e.

1. A set of integers are relatively prime to each other if there is no integer greater than 1 that divides all the elements. Furthermore, in Number Theory, it is known that the Euler function,ϕ (n), expresses the number of positive integers less than n that are relatively prime with n. Choose the alternative that has the correct value of ϕ(n) for every n below. A) ϕ(5) = 4 B) ϕ(6) = 2 C) ϕ(10) = 3 D) ϕ(14) = 6 E) ϕ(17) = 16
Suppose n integers between 1 and 366 are presented as input, and youwant to know if there are any duplicates. How would you solve this problem?What is the rate of growth of the function T(n), describing the time it takes foryou to determine if there are duplicates? (Hint: Pick an appropriate n0.)
Please answer this question in 10 mins i will surely rate your answer. Given an integer string, create all integer permutations of its digits. Determine if there is a permutation whose integer value is evenly divisible by 8, L.e. (permutation value) mod 8 = 0. For example, the possible permutations of 123 are p= (123, 132, 213, 231, 312, 321). Of these values, p[4]-312 is divisible by 8 because 312 mod 8=0. Function Description Complete the function checkDivisibility in the editor below. The function must return an array of result strings, either YES or NO, where each result[i] denotes whether a permutation of arr[i] is divisible by 8. checkDivisibility has the following parameter(s): arr[arr[0]...arr[n-1]): an array of integer strings Constraints • 1≤ns45 Osarris 10110 All characters of arr[i] € (0-9) Input Format for Custom Testing Input from stdin will be processed as follows and passed to the function. The first line contains an integer n, the size of the array arr. Each of the…

The Legendre Polynomials are a sequence of polynomials with applications in numerical analysis. They can be defined by the following recurrence relation: for any natural number n > 1. Po(x) = 1, P₁(x) = x, Pn(x) = − ((2n − 1)x Pn-1(x) — (n − 1) Pn-2(x)), n Write a function P(n,x) that returns the value of the nth Legendre polynomial evaluated at the point x. Hint: It may be helpful to define P(n,x) recursively.
