Python onlyRajesh loves lucky numbers. Everyone knows that lucky numbers are positive integers whosedecimal representation contains only the lucky digits 4 and 7. For example, the numbers 47,744, 4are lucky and 5, 17,467 are not.Let Fa(x) equal the number of digits d in the decimal representation of the positive integer x. Chef isonly interested in F4(x) and F7(x) functions. For a given positive integer N, he wants to know the totalnumber of distinct pairs (L; R) such that F4(L) + F4(L + 1) + ... + F4(R) equals F7(L) + F7(L + 1) + ... + F7(R)and 1

CODE IN PYTHON Colouring Book Having spent the last couple of hours grading assignments, I decide it’s time for a break. I take out my favourite colouring book, turn to a random page I haven’t coloured in yet, and lay it on my desk. I then take out all my n crayons and line them up on the desk (it’s a very long desk). The colour of the ith crayon is a string c[i] (e.g. "blue"). Many of the crayons have the same colour. In fact, no matter how many crayons I have, there are at most 30 distinct colours amongst them. To start colouring, I always take a sublist (see Q1 for a definition) of the crayons laid on the desk and put away the rest (too many options can be overwhelming and can lead to indecision). I take a look at the line art in front of me and wonder, “How many different colours do I need to make this look great? One? Two? Maybe three?”. Now you understand my dilemma and are fully aware of my indecision. You kindly decide to help me out by telling me for every number k, if I were…

= = 2×2 and 6 = (a) A composite number is a positive integer that has at least one divisor other than 1 and itself. For example, 2 1×2 is not a composite number but 4 2 × 3 are composite numbers. A logic circuit has four binary input variables, A, B, C and D. The output Z of the logic circuit is 1 if the unsigned integer represented by the binary number ABCD is a composite number. Using variables A and B for the select inputs S1 and S0 of a 4-to-1 multiplexer, implement the logic function Z(A, B, C, D) using this multiplexor and other logic gates.
Implement a function rollsToRepeat in Python that simulates a dice game in which a pair of dice are rolled repeatedly until some total on the dice occurs the specified number of times. Details: accepts one integer argument, n , the number of repeats required before the game ends rolls a pair of dice repeatedly until some dice total has repeated n times returns the total number of times the pair of dice was rolled For example, using a random seed of 85 , the sequence of rolled pairs will be : (2, 6), (5, 1),(3, 2), (2, 4), (3, 5), (2, 6), (4, 5), (5, 2), (6, 5), (5, 5), ... If you runrollsToRepeat with n=1 , only 1 repeat is required. On the first roll, the total 8=2+6 is repeated once (as wouldany first roll). So the simulation stops and the function returns 1. This always happens whenn=1 . n=2 , some total must repeat twice. This first occurs on the 4throll, when the total of 6occurs for the 2ndtime. n=3 , some total must repeat three times. This first occurs on the 6throll, when…
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++.)

mplement a Java program that applies the Newton-Raphson's method xn+1 = xn – f(xn) / f '(xn) to search the roots for this polynomial function ax6 – bx5 + cx4 – dx3+ ex2 – fx + g = 0. Fill out a, b, c, d, e, f, and g using the first 7 digits of your ID, respectively. For example, if ID is 4759284, the polynomial function would be 4x6 – 7x5 + 5x4 – 9x3+ 2x2 – 8x + 4 = 0. The program terminates when the difference between the new solution and the previous one is smaller than 0.00001 within 2000 iterations. Otherwise, it shows Not Found as the final solution.
The following is a implementation of the Ackermann function: public static long Ackermann(int m, int n){ 0) return n + 1; if (m == else if (n == return Ackermann(m 1, 1); else return Ackermann(m 1, Ackermann(m, n - 1));
In python
Write a function that takes in an array of integers and returns the integers that are either palindromes or almost-palindromes. An almost-palindrome is any integer that can be rearranged to form a palindrome. For example, the numbers 677 and 338 are both almost-palindromes, since they can be rearranged to form 767 and 383, respectively. Examples palindromeSieve ([443, 12, 639, 121, 3232]) [443, 121, 3232] // Since 443 => 434; 121 is a palindrome; 3232 => 2332 or 3223 palindromeSieve([5, 55, 6655, 8787]) → [5, 55, 6655, 8787] // Single-digit numbers are automatically palindromes. palindromeSieve ([897, 89, 23, 54, 6197, 53342]) - []
In loop functions.py, define a function named permutations that takes two paramters, n and r, in that order. This function returns the number of different permutations of length r from set of size n. Essentially to calculate these permutations, the function should compute the product (n - r+1)*(n-r+2)*(n-r+3)*...*(n-2)*(n-1) or n!/(n-r)!. No if statements or built in math functions should be used. For or while loops are best reccomended.
