1) Show the calculation complexity of ciz function as O.
static void ciz(int m) {
for(int i=1; i<=m; i++)
System.out.print("X");
}
2) By using the answer to 1, Show the calculation complexity of main function as O.
import java.util.Scanner;
...
public static void main(String[] arg) {
int n;
Scanner oku = new Scanner(System.in);
System.out.print("N=");
n=oku.nextInt();
for(int m=1; m<=n; m++) {
ciz(m);
System.out.println();
}
}
1. O(m)
Because the loop runs from 1 to m.
2.
1 + 2 + 3 + 4 + ... + n time loop runs
Above equals to n(n+1) / 2
O(n2)
