n and n+1 are integers with the same number of positive divisions. Find the integers n from 1<n<107. For example, the positive divisors of 14 are 1, 2, 7, 14, and 15 are 1, 3, 5, 15. (P.s.: You have to done it by C++.)
Implement the following error detection and error correction algorithms using C programming for Hamming code. For Hamming codes, flip a bit in the data and implement the algorithm to correct the same on the receiver side.
Two n-digit integers (leading zeros allowed) are considered equivalent if one is a rearrangement of the other (for example 12033, 20331 and 01332 are considered equivalent five digit integers.) a) We need to find the number of five digit integers that are not equivalent. b)We need to find the number of non equivalent five digit integers if the digits 1, 3 and 7 can appear at most once. c) When all three digits (1,3,7) appear once.

Correct answer will be upvoted else Multiple Downvoted. Computer science. Polycarp has a most loved arrangement a[1… n] comprising of n integers. He worked it out on the whiteboard as follows: he composed the number a1 to the left side (toward the start of the whiteboard); he composed the number a2 to the right side (toward the finish of the whiteboard); then, at that point, as far to the left as could really be expected (yet to the right from a1), he composed the number a3; then, at that point, as far to the right as could be expected (however to the left from a2), he composed the number a4; Polycarp kept on going about too, until he worked out the whole succession on the whiteboard. The start of the outcome appears as though this (obviously, if n≥4). For instance, assuming n=7 and a=[3,1,4,1,5,9,2], Polycarp will compose a grouping on the whiteboard [3,4,5,2,9,1,1]. You saw the grouping composed on the whiteboard and presently you need to reestablish…
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. Explain what changes are needed to change the 4x3 memory presented on Slide 62 of Chapter 3 to a 16x6 memory.
True or False 1. Matrices are often represented by single small letters a, b, c... etc.2. Two m x n matrices A and B are equal if aij=bij for each i & j. (i.e., the two matrices havesame size, and all the corresponding elements are equal).3. Matrices A & B are said to be conformable in the order AB if, and only if, the number ofrows in A is equal to the number of columns in B.4. Suppose Matrix A is having 4 rows and 3 columns, and Matrix B is having 3 rows and 2columns. The product size of AB is a 4 x 2 matrix.5. Suppose B is the matrix obtained from an n x n matrix A by multiplying the entries in arow/column by a non-zero constant and adding the result to the corresponding entries inanother row/column. Then, det(B) = det(A).
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
Let A be the set of all strings of decimal digits of length 5. For example 24157 and05189 are strings in A.(a) How many strings in A have exactly one 7?(b) How many strings in A have at least two 2’s?(c) How many strings in A have the digits in a strictly decreasing order? For example97643 and 54321 are such strings, but 14820 and 95421 are not.

Post-Lab (Due: Saturday, April 23) Two positive integers are said to be friendly if each one is equal to the sum of the divisors (including 1, excluding the number itself) of the other. For example, the numbers 220 and 284 are friendly since: • sum of divisors of 220 1+2+4+5+10+11+20+22+44+55+110-284 • sum of divisors of 284 1+2+4+71+142-220. Write a C++ program containing the following: • A value returning function that takes as parameter an integer value, num, and returns the sum of its divisors, excluding the number itself. • A main function that enters two positive integer values from the user and makes use of the function written above to print a message that the two values are friendly if each one is equal to the sum of the divisors of the other, and the message that they are not friendly, otherwise.
this is for MPI communication using c++ I need the code for ring communication using mpi Let us assume that k people sit at a round table, the first people produce a random number and send it to the second person; the second people produce a random number, add it up to the received number and send the result to the third people. The procedure continues till the last people aggregate all random numbers and send them back to the first people. The first people print off the aggregated result.
