The best exercise time per day has been revealed by many foreign scholars: the body's ability changes around the clock. Am-Am, am-17 am is the time when the chicken speed, strength, and endurance are relatively optimal. If you perform fitness and sports training during this time, it will receive better results. When-and-14 are in the relatively lowest state, if you are engaged in sports during this time, it is prone to fatigue and the "LOAD" is too la

Aerobic exercise, also known as aerobic metabolic movement, refers to the body's physical activity in the case of adequate oxygen supply. The advantage of aerobic exercise is that it can increase the intake of oxygen, which can better consume excess heat in the body. In other words, in the course of exercise, the human body inhaled oxygen and demand equal, to ach

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

Exercise 4-7 OriginalExercise 4.7. Let* is similar to let, except that the bindings of the A let variables be performed sequentially from left to right, and E Ach binding is made in a environment in which all of the preceding bindings are visible. For example (let* ( (x 3 ) (y (+ x 2 ) ) Span class= "Hljs-list" > (z ( x y 5 ) ) ) (* x z) ) Returns 39. Explain How a let* expression can is rewritten as a set of nested let expressions,

Exercise 4-8 OriginalExercise 4.8. "Named let" are a variant of let that have the formvar>bindings>body>)The and is just as in ordinary let, except that is bound within to a procedure whose body is and whose parameters are the variables in the . Thus, one can repeatedly execute the by invoking the procedure named . For example, the iterative Fibonacci procedure (section 1.2.2) can be rewritten using named let as follows: (Define (fib N) ( LetFib-it
