数组遍

int[] is = new int[1,12,4,546] for(int i=0; i

public static void main(String[] args){ String[] arr = {"a","b","c"}; for(int i = 0; i < arr.length; i++){ System.out.print(arr[i] + " "); } //或者 System.out.println(java.util.Arrays.sort(arr));}

数组的遍历用for循环实现比较好 #include //主函数 main() { int A[10],i,j;//定义数组名与变量名 printf("输入十个数字、回车键确定:\n"); for (i=0;i

如果重复怎么处理?是否需要做区分? 如果忽略重复和反向还原,那么直接用array_merge即可 $new_arr = array_merge($arr['1'],$arr[2]); foreach: foreach($arr as $v=>$k){ foreach($v as $val=>$key){ $new_arr[$key] = $val; }}

#include int main() { int i,num=0,a[6]={0}; do { scanf("%d",num); if(num>0&&num

var arrays1 = ['1','2','3','4','5'],arrays2 = ['a','b','c','d','e'],arrays3 = ['v','w','x','y','z'];var arrays = [];var index = 0;while(true) { if (!arrays1[index] && !arrays2[index] && !arrays3[index]) break; var step = arrays...
