题目一: public class testClockwiseOutput { //顺时针打印一个矩阵 @Test public void test(){ int[][] num = new int[100][100]; int n = 6; int count =1; for(int i=0;i<n;i++){ for(int j =0;j<n;j++){ num[i][j]=count++; } } output(num,0,n-1); } public void output(int[]…
Task description: This is a demo task. Write a function: that, given an array A of N integers, returns the smallest positive integer (greater than 0) that does not occur in A. For example, given A = [1, 3, 6, 4, 1, 2], the function should return 5. G…
