Hlo Bhai where 1st define fun
f(x)=a. : x=1,2,3,,,,,,,,m
x
C. :k>=m.
k-m
This is satisfies 121 fun
Your 1st define function is wrong that is not 11 fun

k

in Ax: x runs from 1 to m
so x covers points from 1 to m
now in another part Cx-m I'm supposed to take those points that aren't common with the above part so here in Cx-m I'm taking x>m i.e x>=m+1
u r saying i should take x>= m thn m is the common point in both partions
thn this is clearly not a disjoint partition
