2. Telephone-Number Word Generator (50) o Standard telephone keypads contain the digits 0-9. The numbers 2-9 each have three letters associated with them, as is indicated by the following table: Digit Letter Digit Letter 2 A B C 6. M N O DE F 7 PR S 4 GH I 8 TU V 5 J KL 9. W X Y o Many people find it difficult to memorize phone numbers, so they use the correspondence between digits and letters to develop seven-letter words that correspond to their phone numbers. o For example, a person whose telephone number is 686-2377 might use the correspondence indicated in the above table to develop the seven-letter word "NUMBERS." Businesses frequently attempt to get telephone numbers that are easy for their clients to remember. If a business can advertise a simple word for its customers to dial, then, no doubt, the business will receive a few more calls. Each seven-letter word corresponds to exactly one seven-digit telephone number. The restaurant wishing to increase its take-home business could…

The Problem A Zeckendorf number is defined for all positive integers as the number of Fibonacci numbers which must be added to equal a given number k. So, the positive integer 28 is the sum of three Fibonacci numbers (21, 5, and 2), so the Zeckendorf number for k = 28 is three. Wikipedia is a satisfactory reference for our purposes for more details of the Zeckendorf and Fibonacci numbers. In both cases, you do not need to read the entire Wikipedia entry. Your assignment is to write two ARM assembly language functions which calculate Zeckendorf and Fibonacci numbers. Zeck function The first function, which should be named zeck, receives an integer parameter in register zero. This will be the variable k we discussed above. Your code should return the Zeckendorf number for k in register zero when complete. If the parameter k is zero, return zero. If the parameter k is negative, return minus 1. If the parameter k is too large to calculate, return minus 1. Fib function The other function,…
F Run a program that tests De Moivre's formula on page 325 by comparing the values obtained from it with those obtained from the recursive definition of the Fibonacci numbers.
Can someone please help me read this because I can barely understand the handwriting
Correct answer will be upvoted else Multiple Downvoted. Computer science. string a will be a substring of a string b if a can be obtained from b by erasure of several (conceivably, zero or all) characters from the start and several (perhaps, zero or all) characters from the end. For example, strings "a", "bc", "abc" are substrings of a string "abc", while strings "ac", "ba", "cba" are not. A string is a palindrome in the event that it reads the same from the passed on to the right and from the right to the left. For example, strings "abccba", "abbba", "aba", "abacaba", "a", and "bacab" are palindromes, while strings "abcbba", "abb", and "ab" are not. Presently Joe wants to track down any right string. Help him! It tends to be demonstrated that the answer always exists under the given constraints. Input Each test contains at least one experiments. The principal line contains the number of experiments t (1≤t≤10). The main line of each experiment contains two integers n and…

Correct answer will be upvoted else downvoted. Computer science. Koyomi has recently gotten the three brief strings from the challenge coordinators. Assist her with composing a substantial novel for the challenge. A string a will be an aftereffect of a string b if a can be acquired from b by erasure of a few (perhaps, zero) characters. Input The principal line contains a solitary integer t (1≤t≤104) — the number of experiments. The principal line of each experiment contains a solitary integer n (1≤n≤105). Every one of the accompanying three lines contains a bitstring of length 2n. It is ensured that these three strings are pairwise unmistakable. It is ensured that the amount of n across all experiments doesn't surpass 105. Output For each experiment, print a solitary line containing a bitstring of length at most 3n that has somewhere around two of the given bitstrings as aftereffects. It very well may be demonstrated that under the imperatives of the…
