  We present high angular-resolution measurements of the thermal
Sunyaev-Zel'dovich effect (SZE) toward two galaxy clusters, RCS J2319+0038 at
z=0.9 and HSC J0947-0119 at z=1.1, by the Atacama Large
Millimeter/submillimeter Array (ALMA) in Band 3. They are supplemented with
available Chandra X-ray data, optical data taken by Hyper Suprime-Cam on
Subaru, and millimeter-wave SZE data from the Atacama Cosmology Telescope.
Taking into account departures from spherical symmetry, we have reconstructed
non-parametrically the inner pressure profile of two clusters as well as
electron temperature and density profiles for RCS J2319+0038. This is one of
the first such measurements for an individual cluster at $z \gtrsim 0.9$. We
find that the inner pressure profile of both clusters is much shallower than
that of local cool-core clusters. Our results consistently suggest that RCS
J2319+0038 hosts a weak cool core, where radiative cooling is less significant
than in local cool cores. On the other hand, HSC J0947-0119 exhibits an even
shallower pressure profile than RCS J2319+0038 and is more likely a
non-cool-core cluster. The SZE centroid position is offset by more than 140
$h_{70}^{-1}$kpc from the peaks of galaxy distribution in HSC J0947-0119,
suggesting a stronger influence of mergers in this cluster. We conclude that
these distant clusters are at a very early stage of developing the cool cores
typically found in clusters at lower redshifts.
