谋求一个问题的解决,把这个问题变形,使之归结为一个熟知的、较易解决的问题,从而求得原问题的解决,这就是化归——解题的基本方法。下面举例说明几种常见的化归方法。 1.化整为零化整为零是指把一个复杂难解的问题分割成若干个简单易解的问题,通过对这些简单问题的解决,达到整个问题解决的方法。
To seek a solution to the problem and distort the problem to a well-known, easier-to-solve problem so that the original problem can be solved. This is the basic method of solving problems. The following examples illustrate several common methods of conversion. 1. Divide into zeros refers to dividing a complex and difficult problem into several easily solvable problems. By solving these simple problems, the entire problem can be solved.
