How is anwser 207

Question

var x = 9;
for(var i=0;i<=10;i++)
{
for(var j=2;j>0;j--)
{
x+=9;
}
}
console.log(x);

Answer 1

var x = 9;
{
for(i=0;i<=10;i++)// 0,1,2,3,4,5,6,7,8,9,10 = 11
{
for( j=2;j>0;j--) /* 0,1 = 2 */
{
x+=9; // 11 * 2 * 9 + 9 = 207
}
}
}
console.log(x);

Answer 2

11×2×9 + 9 = 207

Answer 3

A variable x is declared with value 9. A for loop is there with initial value as 0. and runs till I is equal to 10 so 11 times. Inside this another loop is there with initial value of 2 and runs till j is greater than 0. There it runs two times. x =+ 9 is increasing x value everytime. The loops will increase the value for 11*2 times , i.e. 22 times. 22*9 is equal to 198. The value of x will be 9+198 = 207.

Answer 4

x starts from 9. now, the outer loop executes 11 times, and for each one of them, 2 times +9, so for each outer loop you are doing +18.
11*18 = 198
plus the first 9, 198+9 = 207

Answer 5

hey man. Note that the second loop is inside of first. The first run 11 time and o second 2 time. But the second run 2*11 becouse is inside of first it, in other word, every 1 time of first the second run 2 time in second. Look:
0 = +9 +9 = 18
1 = +9 +9 = 36
2 = +9 +9 = 54 ...
until 10 (11 times)
+9 value of x.

Answer 6

first loop will run 11 times and 2nd will 2 times
hence 11*2=22 times
but 9 already assigned to x so total 23
ie 9+9+9+ - - -(23 times)=9*23=207

Answer 7

var x = 9;
{
for(i=0;i<=10;i++)// 0,1,2,3,4,5,6,7,8,9,10 = 11
{
for( j=2;j>0;j--) /* 0,1 = 2 */
{
x+=9; // 11 * 2 * 9 + 9 = 207
}
}
}
console.log(x);

Answer 8

Wow, this question along with responses have helped me understand multiplication can help me quickly calculate through loops. Thanks!

Answer 9

var x=9;
function funcInLoop(){
return 9*2;
}
for(i=0;i<=10;i++){
x += funcInLoop();
}
console.log(x)

Don't use loop inside loop. It's best use recursive function, or a function it. The loop get many resources.

Look:

for (var i=0;i<= 10;i++){
/* put the function here inside. */
funcInLoop(test);
/* This function should exist. */

}

Mr Genesis de Souza Rosa Genesis what if there is a for loop in funcInLoop?
