小白笔记------------------leetcode(412. Fizz Buzz )

Write a program that outputs the string representation of numbers from 1 to n.

But for multiples of three it should output “Fizz” instead of the number and for the multiples of five output “Buzz”. For numbers which are multiples of both three and five output “FizzBuzz”.

Example:

n = 15,

Return:
[
    "1",
    "2",
    "Fizz",
    "4",
    "Buzz",
    "Fizz",
    "7",
    "8",
    "Fizz",
    "Buzz",
    "11",
    "Fizz",
    "13",
    "14",
    "FizzBuzz"
]

注意二维字符串数组的malloc，先确定行数，然后为每行创造空间；注意二维字符串数组每行的赋值用*(p+i)的方式

/**
 * Return an array of size *returnSize.
 * Note: The returned array must be malloced, assume caller calls free().
 */
char** fizzBuzz(int n, int* returnSize) {
    char **result;
    int i = 0, m =16;
    result =(char **)malloc( n*sizeof(char *) ); 
    for(i = 0;i < n;i++ )
    {
        result[i]=(char *)malloc( m  * sizeof(char) ); 
    }

    for(i=0;i
