Exercise 3-3 the last three bits of the productEnter several words, enter a number of integers (which can be positive, negative, or 0), and output the last three bits of their product. These integers are mixed with a string of uppercase letters, and your program should ignore them. Tip: Try to enter a string when executing scanf ("%d").#include Summary: 1 Note overflow2 for a break in the bad, the next code is to determine where the for-through-bad ex

Exercise 2.70Now that you want to decode it, you have to define the tree first.(DefineTree(generate-huffman-tree '((A 2) ( NA ) ( BOOM 1) ( SHA 3) (GET 2) ( YIP 9) (JOB 2) (WAH 1)) And then just to encode the lyrics given in the question.(define message-1 '(Get a job))(define message-2 '(Sha nana- na na na na na na))(define message-3 '(Wah Yip Yip Yip Yip Yip Yip Yip Yip Yip))(define message-4 '(Sha Boom)) (encode message-1 tree); Value: (1 1 0 0

Exercise 4-5 OriginalExercise 4.5. Scheme allows an additional syntax for cond clauses, (= =). If evaluates to a true value, then is evaluated. Its value must is a procedure of one argument; This procedure was then invoked on the value of the, and the result is returned as the value of the the COND expression. For example(cond ((assoc ‘b ‘((a 1) (b 2))) => cadr) (else false))Returns 2. Modify the handling of cond so, it supports this extende

Exercise 4-6 OriginalExercise 4.6. Let expressions is derived expressions, because(Let () ... ( )) )is equivalent to((Lambda (...)))Implement a syntactic transformation let->combination that reduces evaluating let expressions to evaluating combination S of the type shown above, and add the appropriate clause to eval-handle let expressions.AnalysisThis problem requires that we convert let expressions into corresponding expressions.(Let () ... ( )) )Fro

Exercise 4-4 OriginalExercise 4.4. Recall the definitions of the special forms and and or from Chapter 1:And:the expressions is evaluated from left to right. If any expression evaluates to False, False is returned; Any remaining expressions is not evaluated. If all the expressions evaluate to true values, the value of the last expression is returned. If there is no expressions then true is returned.Or:the expressions is evaluated from left to right. I

Exercise 4-1 OriginalExercise 4.1. Notice that we cannot-whether the Metacircular evaluator evaluates operands from left to right or from right to left. Its evaluation order was inherited from the underlying lisp:if the arguments to cons in List-of-values was evaluated from Left-to-right, then list-of-values'll evaluate operands from left to right; And if the arguments to cons is evaluated from right to left, then list-ofvalues'll evaluate operands fr

Exercise 3-77 OriginalExercise 3.77. The integral procedure used above was analogous to the "implicit" definition of the infinite stream of integers 3.5.2. Alternatively, we can give a definition of integral that's more like Integers-starting-from (also in section 3.5. 2):(Define (integral integrand initial-value DT) (cons-stream initial-value (if (stream-null integrand) /c5> the-empty-stream (integral (stream-cd R integrand)(+ (* DT (stream-car int

Exercise 3-66 OriginalExercise 3.66. Examine the stream (pairs integers integers). Can you do any general comments about the order in which the pairs is placed into the stream? For example, about how many pairs precede the pair (1,100)? The pair (99,100)? The pair (100,100)? (If you can make precise mathematical statements this, all the better. But feel-give more qualitative answers if you find yourself getting bogged down.)AnalysisThere are two scena

Exercise 1.20This problem requires us to study the GCD function in the book in the context of both the regular order and the application sequence, and also to figure out the number of actual remainder operations performed.The first question in the question is the application sequence, but since the application sequence is relatively simple, let's take a look at the application sequence:(GCD 206 40)(GCD 40 6)(GCD 6 4)(GCD 4 2)(GCD 2 0)2Therefore (GCD 2

If you do not pay attention to the scientific nature of fitness, you will not be able to achieve the effect of exercise. Experts pointed out that fitness should be taken before Sunday and follow the principles of safety, proper quantity, and gradual progress. Otherwise, the fitness effect may be half the effort. In the past, many people thought that the sooner they got up, the better their health. So they often started outdoor exercises when they wer

Three digits in reverse order (Exercise on the first day), exercise on the first day of Reverse Order Subject content: Each time the program reads a positive three-digit number, it then outputs a number in reverse order. Note: When the input number contains 0 at the end, the output should not contain 0 at the beginning. For example, if the input value is 700, the output value is 7. Input Format: Each te
