$\displaystyle{x^2}$ Laid Down On The Floor

Calculus Level 4

$\large \int_{1}^{2} \left(x^{\lfloor x^2 \rfloor} + {\lfloor x^2 \rfloor}^{x} \right) \, dx$

The integral above can be expressed as $\dfrac{a}{b} + \sqrt{c} + \dfrac{\sqrt{d}}{e} + \dfrac{2^{\sqrt{f}}-2^{\sqrt{g}}}{\ln h } + \dfrac{i - 3^{\sqrt{j}}}{ \ln k}.$ What is the sum of all of these constants from $\displaystyle{a}$ to $\displaystyle{k}?$
