Approach

Step-i) initialize i to 1
Step-ii) initialize j to 1
Step-iii) print the value of the j and space (" ")
Step-iv) increment j value by one
Step-v) repeat steps iii to iv till j is less than or equal to i
Step-vi)go to next line and increment i value by one
Step-vii)repeat steps ii to vi till i is less than or equal to N

Time Complexity: O(n^2)
Space Complexity: O(1)
