It is said that our famous mathematician, Hua Luogeng, saw a puzzle in a magazine that a passenger next to him was reading on a plane during a visit abroad. The puzzle was: a number is $59319$, and the cube root of it is sought. Hua Luogeng blurted out: $39$. The passenger next to him was very surprised and asked about the secret of the calculation. Hua Luogeng gave the following method: (1) By knowing that $10^{3}=1000$, $100^{3}=1000000$, it is determined that $\sqrt[3]{59319}$ is a two-digit number; (2) By knowing that the units digit of $59319$ is $9$, it is determined that the units digit of $\sqrt[3]{59319}$ is $9$; (3) By subtracting the last three digits $319$ from $59319$ to get $59$, and since $3^{3}=27$, $4^{3}=64$, it is determined that the tens digit of $\sqrt[3]{59319}$ is $3$. Please follow the above process to determine the cube root of $21952$.
