800. Similar RGB Color
Problem Explanation
Explanation:
To solve this problem, we need to find the closest valid color representation for a given color. The problem requires us to find the closest color in a predefined color list to the given color. We can achieve this by converting the given color to its closest valid color by rounding each color channel to the nearest multiple of 17 (hexadecimal representation).
- Convert the given color to its hexadecimal representation.
- For each channel (R, G, B), find the closest multiple of 17.
- Convert the rounded values back to decimal representation.
- Return the closest valid color. :
Solution Code
class Solution {
public String similarRGB(String color) {
return "#" + getClosestColor(color.substring(1, 3)) + getClosestColor(color.substring(3, 5)) + getClosestColor(color.substring(5, 7));
}
private String getClosestColor(String channel) {
int value = Integer.parseInt(channel, 16);
int closest = Math.round(value / 17) * 17;
return String.format("%02X", closest);
}
