I recently started learning Java and was solving problems on HackerRank when I came across this one. I couldn’t figure it out and started feeling pretty down, thinking I must be too dumb to solve even the “easy” problems. But it turns out this one wasn’t as easy as it looked, which makes me feel a bit better.

the "1" in the series (1.2 + b) is the exponent of 2 °, it is called "zero rule" every number to zero is equal to 1

[ShajahanSmart]

this much tough and they kept that in easy ecction

[matthewstaton]

This is listed as "Easy" on hackerrank. Though there isn't much to it, I wouldn't call it easy tbh...

This shit destroy me in 3 days and have to gain energy to comeback.

[zeyaddessouki]

Keep going please thx alot, that really helped

[iamniravkumarpatel]

Thanks for the video, helped a lot. Keep doing the great work. Subscribing for more content.

u can replace that 2 with "t" other wise it wont work with other 1st input then 2
thanks for solution.
Edit:Nah doesnt work replacing t with 2

[leonardonitolemoreira]

I did this and i think it's way better to understand what's going on
for (int j = 0; j < n; j++) {
System.out.print( a += Math.pow(2, j) *b ); //literally the formula given
System.out.print(" ");
}
System.out.print("\n");

Oh. so I didn't have to input a, b, and c all into one String variable like it said in the "sample input", and then convert each number from that String into an int, and store it somewhere... Darn it. If you haven't shared this I may have wasted another 3 hours on it. Thanks.

hi bro my name is kiran from india slove the problem

[bornfinder]

for(int j=0;j<n;j++){
a+=b;
System.out.print(a+" ");
b=b*2;
}
System.out.println();
bro love you
no need of if statement

[sudenursenkal]

my solution :
import java.util.*;
import java.io.*;

class Solution{
public static void main(String []argh){
Scanner in = new Scanner(System.in);
int t=in.nextInt();
for(int i=0;i<t;i++){
int a = in.nextInt();
int b = in.nextInt();
int n = in.nextInt();

int y = a + b;
System.out.print(y + " ");
for(int j = 1; j<n ; j++){
int c = (int) Math.pow(2, j);
y = y + c * b;
System.out.print(y + " ");

}
System.out.println();
}
in.close();
}
}
