An expression of the form 2 a = a, + az +a, + + a, + ... is called an infinite series. The letter k is called the index of summation and takes on values from the lower bound (which is 1 here) to the upper bound (which is infinity here). The dots mean that we are to continue the addition indefinitely. However, it is not practical to keep adding the terms indefinitely; we should be able to stop at some point. Hence, we need a criterion to stop the summation. The sum of part of the sequence is a partial sum. Usually, we either have to calculate the sum of the first n terms of a series or stop the summation when a term becomes less than some pre-defined tolerance value.

Given two strings A and B, find the minimum number of times A has to be repeated such that B is a substring of it. If no such solution, return -1.For example, with A = "abcd" and B = "cdabcdab".Return 3, because by repeating A three times (“abcdabcdabcd”), B is a substring of it; and B is not a substring of A repeated two times ("abcdabcd").Note:The length of A and B will be between 1 and 10000.Reference: https://leetcode.com/problems/repeated-string-match/description/"""def repeat_string(A, B): count = 1 tmp = A max_count = (len(B) / len(A)) + 1 while not(B in tmp): tmp = tmp + A if (count > max_count): count = -1 break.
For the definition of x ∈ EXPR , na(x) denotes the number of a’s in the string, and we will use nop(x) to stand for the number of operators in x (the number of occurrences of + or ∗). Show that for every x ∈ EXPR, na(x)= 1 + nop(x).
There are many algorithms presented in this text that would lend themselves to beincluded as subprograms in the utils.asm file. Implement some or all of the followinginto the utils.asm file, properly documenting them, and include programs to test them.a. NOR subprogram - take two input parameters, and return the NOR operation onthose two parameter.b. NAND- take two input parameters, and return the NAND operation on those twoparameter.c. NOT- take one input parameters, and return the NOT operation on that parameter.d. Mult4 - take an input parameter, and return that parameter multiplied by 4using only shift and add operations.e. Mult10 - take an input parameter, and return that parameter multiplied by 10using only shift and add operations.f. Swap- take two input parameters, swap them using only the XOR operation.g. RightCircularShift - take an input parameter, and return two values. The firstis the value that has been shifted 1 bit using a right circular shift, and the second isthe…

Consider a logic function with inputs A, B, and C defi ned as follows: ■ If A or C is true, then output D is true, whatever the value of B. ■ If A or B is true, then output E is true, whatever the value of C. ■ Output F is true if exactly one of the inputs is true, although we don’t care about the value of F, whenever D and E are both true. Show the full truth table for this function and the truth table using don’t cares. How many product terms are required in a PLA for each of these?
From the example suggested, this is the output I get if we run the code:n = 4 arcs = [(0, 3), (1, 2), (4, 7), (5, 6), (8, 11), (9, 10), (12, 15), (13, 14)]crossings, nestings = count_crossings_and_nestings(arcs) print(f"Number of crossings: {crossings}")print(f"Number of nestings: {nestings}")However, upon closer inspection of the code, the function is not working as expected because there's an issue with the logic: the condition checks for nestings are repeated.It should be checking for one case where the start of one arc is between the start and end of another arc, and the end of one arc is between the start and end of another arc. The same condition is used twice in the code. And I tried computing nestings and crossings with the smallest examples below: def count_crossings_and_nestings(arcs): n = len(arcs) // 2 crossings = 0 nestings = 0 for i in range(2 * n): for j in range(i + 1, 2 * n): if arcs[i][0] < arcs[j][0] < arcs[i][1] < arcs[j][1]:…
