PLS HELP ME ! What's the dry running program of this Input :
// Java program to illustrate for loop.
class forLoopDemo {

public static void main(String args[]){

int sum = 0;

// for loop begins
// and runs till x <= 20
for (int x = 1; x <= 20; x++) {

sum = sum + x;

}
System. out. println("Sum: " + sum);

}

}
Output :
Sum : 210

The “rule of 72” is used to approximate the time required for prices to double due to inflation. if the inflation rate is r%, then the rule of 72 estimates that prices will double in 72/r years. for instance, at an inflation rate of 6%, prices double in about 72/6 or 12 years. write a program to test the accuracy of this rule. for each interest rate from 1% to 20%, the program should display the rounded value of 72/r and the actual number of years required for prices to double at an r% inflation rate. (assume prices increase at the end of each year.)
