Print the unique element in an array
Problem to print the unique element in an array. Unique elements means without repeating character.
Example-1:
Input : s = [ "A", "B", "C", "D", "E", "A", "C"] Output : B D E Explain : Unique elements are (B,D,E).
Example-2:
Input : s = [ "H", "E", "L", "L", "O"] Output : H E O Explain : Unique elements are (H,E,O).
Solution
public class Main
{
public static void main(String [] args)
{
char ch [] = {'A', 'B', 'C', 'D', 'E', 'A', 'C'};
for(int i = 0; i<ch.length; i++)
{
if(ch[i] == '\0') continue;
for(int j = i+1; j<ch.length; j++)
{
if(ch[j] == '\0') continue;
if(ch[i]==ch[j])
{
ch[i] = '\0';
ch[j] = '\0';
}
}
}
for(int i = 0;i<ch.length;i++)
{
if(ch[i] != '\0')
{
System.out.print(ch[i]+" ");
}
}
}
}
n = [ "A", "B", "C", "D", "E", "A", "C"]
for i in range(len(n)):
if(n.count(n[i])==1):
print(n[i],end=" ")
Output
B D E
