Define a counter, one output at a time, and the counter to accumulate 1. The value of this counter is the value we want to print.//2. The line number is the same as the number of elements in this line, so we can use the line number to control the inner loop//3. Output counter in inner loop//output line wrapping inside the outer loop Public classT1 { Public Static voidMain (string[] args) {intCount=1;  for(intx=0;x<6;x++){             for(inty=0;y<=x;y++) {System.out.print (Count+ "\ T"); Count++;        } System.out.println (); }    //instead of outputting n rows n columns of triangular digital arrayScanner sc=NewScanner (system.in); System.out.println ("Please enter number n"); intn=Sc.nextint (); Count=1;  for(intx=0;x<n;x++){             for(inty=0;y<=x;y++) {System.out.print (Count+ "\ T"); Count++;        } System.out.println (); }    }}
