## 1). Print Left Half Diamond Pattern using Star(*) and Hyphen(-) in Java

import java.util.*;
class Main{
public static void main(String ...a){
int i,j,k;
Scanner sc= new Scanner(System.in);
System.out.print("enter the value n: ");
int n= sc.nextInt();
for(i=0;i<n;i++)
{
for(j=0;j<n-i;j++){
System.out.print(" ");
}
if(i%2==0){
for(k=0;k<=i;k++){
System.out.print("*");
}
}else{
for(k=0;k<=i;k++){
System.out.print("-");
}
}
System.out.println("");
}
for(i=n-1;i>0;i--)
{
for(j=n;j>=i;j--){
System.out.print(" ");
}
if(i%2==0){
for(k=i;k>0;k--){
System.out.print("-");
}
}else{
for(k=i;k>0;k--){
System.out.print("*");
}
}
System.out.println("");
}
}
}
