The copy code is as follows:

Php Bubble sort 2

The basic concept is to compare two adjacent numbers in turn, putting the decimal in front and the large number in the back. That is, first compare the first and second numbers, putting the decimal before the large number. Then compare the second number and the third number, put the decimal before the large number, and so on, until you compare the last two numbers, put the decimal before the large number. Repeat the above process, still start from the first logarithm (because it is possible that the first number is no longer less than the second number due to the exchange of the second number and the third number), put the decimal number before, after the large number, compare to a pair of adjacent numbers before the maximum number, put the decimal number before, after the large number, at the end of the second round, and get a new maximum number in the penultimate number. Go on like this until the sorting is finally completed.

Because decimals are always put forward and large numbers are put back in the sorting process, which is equivalent to the rise of bubbles, it is called bubbling sorting.

It is realized by a double loop, with the outer loop variable set to I and the inner loop variable set to j. The outer cycle was repeated 9 times, and the inner cycle was repeated 9 times in turn. The two elements compared each time are related to the inner loop j, and they can be identified by a [j] and a [j + 1] respectively. The value of I is 1, 2, respectively. For each I, j

The values are in the order of 1, 2, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 2, 5, 5, 5, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4 and 4 respectively.
