Floyd’s Triangle – Java Implementation
Floyd’s Triangle:
- Floyd’s triangle is a right angled triangular array of natural numbers.
- It named after Robert Floyd.
- Rows of the triangle filled by consecutive numbers.
- First row will have single number which is 1.
- Second row will have two numbers, which are 2 and 3
- Third row will have three numbers, which are 4, 5 and 6..
- And so on
Example:
First 5 lines… 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Approach:
- Two nested loops.
- Outer loop will take care for rows.
- Inner loop will take care of printing the numbers.
- Line break after each iteration of inner loop.
- Keep track of numbers printed so far in a variable.
- See the code for more understanding.
Code:
Output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28
