- KAUJ RUAM 2: DEFINE Cov hlua hlua = "Qhov zoo tshaj plaws ntawm ob lub ntiaj teb".
- KAUJ RUAM 3: SET suav = 0.
- Kauj ruam 4: SET i=0. Rov ua dua KAUJ RUAM 5 txog Kauj Ruam 6 kom txog rau thaum i<string.length.
- Kauj ruam 5: IF (string. charAt(i)!= ' ') ces suav = suav +1.
- Kauj ruam 6: i=i+1.
- Kauj ruam 7: PRINT suav.
- KAUJ RUAM 8: TUG.
