Saat dost ek ke peeche ek line mein khade hain. Har koi ek niyam se number bolta hai: mere aage kitne log mujhse lambe hain? Lambaai (cm mein) 140, 152, 135, 160, 128, 149, 131. Ve bolte hain 0, 0, 2, 0, 4, 2, 5.

0, 0, 2, 0, 4, 2, 5

Ek jaancho: 5vi dost (128 cm) ke aage 140, 152, 135 aur 160, sab lambe, to wo 4 bolti hai. Numbers lambaai bataaye bina lambaai ka kram bataate hain. Pehla vyakti hamesha 0 bolta hai, kyunki aage koi nahi.

Hamesha, kabhi-kabhi ya kabhi nahi? Sabse lamba hamesha 0 bolta hai (aage koi lamba nahi). Par 0 bolne wala sirf kabhi-kabhi sabse lamba: shayad wo bas aage walon se lamba hai. 8 ki line mein sabse bada sambhav number 7: aakhri vyakti, agar sabse chhota.

Line banao: 0, 1, 2, 3, 4, 5, 6 ke liye har koi aage walon se chhota ho, to sabse lambe se sabse chhote tak khade ho. 0, 0, 0, 0 … ke liye chhote se lambe tak. Doston ke saath 0, 1, 0, 1, 0, 1, 0 banaakar dekho!

Explore: hamesha, kabhi-kabhi ya kabhi nahi?

1. Line ke khel ke kathan sort karo.

Yaad rakho

• Niyam lambaai ko aise numbers mein badalta hai jo asli lambaai bina kram dikhaate hain.
• Kathan ko aisi line dhoondhkar jaancho jahan wo na chale.
