One master process aggregates and sums the result of $n$ slave$-$processes where each slaveprocess sums a different range of values in an array of $1000$ random integers $($please program to generate $1000$ integers to populate the array$).$

The number of slave$-$processes $n$ is a parameter which the user can change. For example, if the user chooses $4$ slave processes, each slave process will sum $\frac{1000}{4}=250$ numbers. If the user chooses $3$ slave processes, the first two may each sum $333$ numbers and the third slave process sums the rest $334$ numbers.
