\delta(x,i) &= min\left[ i, \ceil{\frac{x}{c}} \right]\\  A_1 &= \sum_{k=1}^{\delta(x,i)}\Big[ 2(k - 1) \Big]\\  &= 2\sum_{k=1}^{\delta(x,i)}\Big[ k \Big] - \sum_{k=1}^{\delta(x,i)}\Big[ 1 \Big]\\  &= \delta(x,i)(\delta(x,i) + 1) - \delta(x,i)  A_2 &= \Big( 2\delta(x,i) - 1 \Big)\Big( i-\delta(x,i) \Big)\\  &= 2i\delta(x,i) + \delta(x,i) - 2\delta(x,i)^2 - i\\  T(i,x) &= A_1 + A_2
