Program to print binary right angle triangle

Last Updated : 16 Feb, 2023

Binary right angle triangle consists of only 0’s and 1’s in alternate positions.
Examples :

Input : 4
Output :
         0    
         1    0    
         0    1    0    
         1    0    1    0

Input : 3
Output : 
         0    
         1    0    
         0    1    0
