Balance UI Sliders

Question

Hi! I have 4 UI sliders whose values I want to sum equal to or less than 100. I've been trying to figure this out by myself for a while, but I'm still very new to this, so I'm having a bit of trouble. Any help would be appreciated :) Here is what I currently have:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 
 public class StatBalance : MonoBehaviour
 {
     private float[] set;
     public float sliderValue1 = 0f;
     public float sliderValue2 = 0f;
     public float sliderValue3 = 0f;
     public float sliderValue4 = 0f;
 
     void Start()
     {
         set = new float[4];
         set[0] = sliderValue1;
         set[1] = sliderValue2;
         set[2] = sliderValue3;
         set[3] = sliderValue4;
     }
 
     void AdjustValues()
     {    
         // balance set of values here
     }
 
 
         /// Note: these sliders have a range of 0f to 100f
     public void SliderValue1(float uiSliderValue1)
     {
         sliderValue1 = uiSliderValue1;
     }
 
     public void SliderValue2(float uiSliderValue2)
     {
         sliderValue2 = uiSliderValue2;
     }
 
     public void SliderValue3(float uiSliderValue3)
     {
         sliderValue3 = uiSliderValue3;
     }
 
     public void SliderValue4(float uiSliderValue4)
     {
         sliderValue4 = uiSliderValue4;
     }
 }

 using UnityEngine.UI;
     
 public class StatBalance : MonoBehaviour
 {
     [SerializeField] private Slider[] sliders;
     private float[] values;
 
     // Start is called before the first frame update
     void Start()
     {
         if (sliders.Length > 1)
         {
             for (int sliderIndex = 0 ; sliderIndex < sliders.Length ; sliderIndex++)
             {
                 int i = sliderIndex;
                 Slider slider = sliders[sliderIndex];
                 SetRatio(slider, 1f / sliders.Length);
                 slider.onValueChanged.AddListener(_ => BalanceSliders(i));
             }
             values = Array.ConvertAll(sliders, GetRatio);
         }
     }
 
 
     private void BalanceSliders(int updatedSliderIndex)
     {
         Slider updatedSlider = sliders[updatedSliderIndex];
 
         for (int sliderIndex = 0 ; sliderIndex < sliders.Length ; sliderIndex++)
         {
             if (sliderIndex != updatedSliderIndex)
             {
                 Slider slider = sliders[sliderIndex];
 
                 float ratio = values[updatedSliderIndex] >= 1f - Mathf.Epsilon
                     ? 0
                     : values[sliderIndex] / (1 - values[updatedSliderIndex]);
                 float value = (1 - GetRatio(updatedSlider)) * ratio;
 
                 SetRatio(slider, value);
             }
         }
 
         for (int sliderIndex = 0 ; sliderIndex < sliders.Length ; sliderIndex++)
         {
             values[sliderIndex] = GetRatio(sliders[sliderIndex]);
         }
     }
 
     private float GetRatio(Slider slider)
     {
         return Mathf.InverseLerp(slider.minValue, slider.maxValue, slider.value);
     }
 
     private void SetRatio(Slider slider, float ratio)
     {
         slider.SetValueWithoutNotify(Mathf.Lerp(slider.minValue, slider.maxValue, ratio));
     }
 }
