Just keep on trying, the answer will come up, my algorithm was something like this
create a "cumulative" variable and set it equal to user input "a"
Inside the INPUT FOR Loop
1)Create a new for loop for a variable say "j", start it from 0 to n where n is the input provided by user and already written in the code.
2)compute the part of (2^j)*b and store it in a variable say "res".
3) Now simply add the equation to the cumulative variable -> cumulative=cumulative+res(refer step 2)
4) Print (cumulative+" ")
5) Close for loop
6) user proper Println syntax tomove cursor to next line.
and also you have to display the answer in two lines you cannot enter the next line
such as if you have two different set of values as answer you have to display them in two lines but with your program after that you are entering the third line
that a is added n times in last term of series
and n-1 times in second last term of series
and n-2 times in third last term of series
......
.....
.....
and a is added only once in each term of series.
So u can print
System.out.println(v+a); instead of adding the a in each term.

Hey,
Just keep on trying, the answer will come up, my algorithm was something like this create a "cumulative" variable and set it equal to user input "a" Inside the INPUT FOR Loop 1)Create a new for loop for a variable say "j", start it from 0 to n where n is the input provided by user and already written in the code. 2)compute the part of (2^j)*b and store it in a variable say "res". 3) Now simply add the equation to the cumulative variable -> cumulative=cumulative+res(refer step 2) 4) Print (cumulative+" ") 5) Close for loop 6) user proper Println syntax tomove cursor to next line.
class Solution{ public static void main(String []argh){ Scanner in = new Scanner(System.in); int t=in.nextInt(); int v=0; for(int i=0;i
}
//can you help me where i went wrong
class Solution{ public static void main(String []argh){ Scanner in = new Scanner(System.in); int t=in.nextInt(); for(int i=0;i
}
you can not use ^ in java (i guess in programming ) use Math.pow(arg1,arg2) check this for more detail
check my code @ https://codeshare.io/arJ93q ask me if any issue or you can inhence my code -thank you
You can use the '^' in programming. Python, Pearl, (not sure if on Ruby is possible) are some languages that support the use of '^'.
isn't ^ XOR
u cant add " a " sum it will disturb the sum just substitute and check
^ operator is not supported in java
yes, instead of this use Math.pow() operator..... Hope this is helpful!!!!
for(int i=0;i
smart and excellent
for Math.pow j has to be double, it won't work
use type cast int as pow returns double and this code won't pass all the testcases. You need to use long to pass all the testcases
and also you have to display the answer in two lines you cannot enter the next line such as if you have two different set of values as answer you have to display them in two lines but with your program after that you are entering the third line
you cant use to the power here(2^j) you have to use math.pow() function
that a is added n times in last term of series and n-1 times in second last term of series and n-2 times in third last term of series ...... ..... ..... and a is added only once in each term of series. So u can print System.out.println(v+a); instead of adding the a in each term.
println itself means a new line so make it like
System.out.println();
Everything
