An example of an arbitrary number sequence is provided below:
const numbers = [
0, 0, 0, 0, 0,
12, 64, 9, 6,
0, 0, 0,
25, 79, 57, 13, 39,
0, 0,
7, 7,
0, 0, 0, 0, 0,
49,
0
];
The task at hand is to replace all zero values with interpolated values derived from their non-zero neighbors. The expected output for the updated sequence is as follows:
const updatedNumbers = [
12, 12, 12, 12, 12,
12, 64, 9, 6,
10.75, 15.5, 20.25,
25, 79, 57, 13, 39,
28.3333, 17.6666,
7, 7,
14, 21, 28, 35, 42,
49,
49
];
In cases where a zero value is located at the beginning or end of the sequence without both left and right non-zero neighbors, the zero value is replaced accordingly.
The code snippet provided demonstrates a solution to this problem by identifying sequences of zeros in the initial array, finding their neighboring non-zero elements, and then calculating and replacing the interpolated values within those sequences.
