Subtracting all the elememts in an array by X digit for K number of times

Question

I want to print two arrays like, if the array is arr[]={1,2,3,4}
K=2-Number of times array must repeatedly be subtracted.
X=3-Elements must be subtratacted with this digit.
So array must change as,
for K=1(A): arr={|1-3|,|2-3|,|3-3|,|4-3|}
for K=2(B): arr:{|2-3|,|1-3|,|0-3|,|1-3|}
Output: A:2,1,0,1
B:1,2,3,2.
arr={3,5,6}
K=3 X=2
K=1(A): {1,3,4}
K=2(B): {1,1,2}
K=3(A): {1,1,0}
Output: A:1,1,0
B=1,1,2

Answer 1

class Test{
public static void arrCalc(int[] arr, int k, int x){
int[] A = new int[arr.length];
int[] B = new int[arr.length];
for(int i=0;i<k;i++){
for(int j=0;j<arr.length;j++){
arr[j] = Math.abs(arr[j]-x);
if(i%2==0)
A[j] = arr[j];
else
B[j] = arr[j];
}

}
System.out.print("A: ");
for(int i:A)
System.out.print(i+" ");
System.out.println();
System.out.print("B: ");
for(int i:B)
System.out.print(i+" ");
}
public static void main(String[] args) {
int[] arr = {3,5,6};
int k = 3;
int x = 2;
arrCalc(arr, k, x);

}
}

Answer 3

Interesting task. Can I confirm some things first?

1. In which language, cause it's done differently by language.

2. Should the subtraction result be absolute? cause I see no negative values.

3. You said "to print two arrays ..." but if <K> was more than two, then there would be <K> arrays generated, if I understood it correctly ...

P.S. It would be nice to see your tryout code first, so please attach your code link in post's Description ☝

Answer 4

Ipang yeah
2. absolute as he wrote |a-b|
3. He expects last 2 Arrays

PleaseCodeForMe? Yeeeeeah....maybe
Decided to do a special approach that at least is not good for school.😁

Found a more efficient than direct approach
