JavaScript Calculation Beer 2 yuan a bottle, 4 cover for a bottle, 2 bottles for a bottle, 10 yuan to drink the most bottles

Tag: Push otherwise performs function nbsp Loop log Assignment Func

var n = 0//How many bottles are left now plus how many bottles are won?

var x = 5//Initial number of bottles

var y = 0//How many bottles are left in addition to the drink

var z = total number of 0;//

var arr = []//defines an array of stored values

Arr.push (x);//Add the initial bottle number to the array first

Procedure 1

var fn = function (s) {

y = s-4; How many bottles are left?

s = y + parseint (S/4) + parseint (S/2);//How many bottles are left plus how many are won?

n = s//assignment to the above n

Arr.push (n);//Add to Array

if (n>=4) {//If there are many bottles left plus how many bottles are greater than or equal to 4

FN (n);//Continue executing program 1

}else{//otherwise

FN1 (n)//Execute Program 2

}

}

Procedure 2

var fn1 = function (s) {

y = How many bottles are left in s-2;//

s = y + parseint (S/2);//How many bottles are left plus how many are won?

n = s//assignment to the above n

Arr.push (n);//Add to Array

if (n>=2) {//If there are many bottles left plus how many bottles are greater than or equal to 2

FN1 (n);//Continue to execute program 2

}

}

FN (x)//Execute Program 1

for (Var i=0;i<arr.length;i++) {

z + = arr[i]//Loop array add up all the numbers

}

Console.log (z);//Get Totals and Print

Logic:

1, first drink 4 bottles, the remaining 1 bottles, plus 2 bottles and 1 bottles, left 4

2, then drink 4 bottles, 0 bottles left, plus 2 bottles and 1 bottles, leaving 3 bottles.

3, then drink 2 bottles, the remaining 1 bottles, plus 1 bottles, the remaining 2 bottles

4, then drink 2 bottles, the remaining 0 bottles, plus 1 bottles, the remaining 1 bottles

5, add up the number is, 5+4+3+2+1 = 15
