$1.$ Create a vector $(1$D array$)$ of size $20.$ All the elements are initialized with $0($zero$)$ except for the $8$th element that is set with the value $8.2.$ Create a vector of size $16$ with random values ranging from $0$ to $63,$ print the vector, then sort it and print the vector again. $3.$ Create a $5$x$5$ matrix with values ranging from $0$ to $24.4.$ Create an $8$x$8$ array with random values, then find the min and max values stored in this matrix. $5.$ Create a vector of size $32$ that is initialized with random values inside the range $(0,99)$ and then find the mean of all the initial values.
