double average(int* salary, int salarySize){
    int min=1000000,max=1000,i,sum=0;
    for(i=0; i<salarySize; i++){
        if(salary[i]<min) 
            min=salary[i];
        if(salary[i]>max)
            max=salary[i];
        sum += salary[i];
    }
    return (sum-min-max)/(double)(salarySize-2);
