Is it possible to reduce the cost of this function with a for loop?

Question

Is it possible to reduce the gas cost of this function? It's currently at 140k gas for 20 elements. (I'm new to solidity)

uint8[1000] public array;

function Test(uint32[] index, uint8[] value) public  {        
    for (uint i=0; i<index.length; i++) {
        array[index[i]] = value[i];
    }
}

Answer 1

Have you tried creating a mapping of the index and the value instead of creating two separate arrays? It would work in certain situations but this code doesn`t tell me anything.

//Creating the mapping:
mapping(uint32 index => uint8 value) theMap;
//Then when setting the value:
theMap[index] = value;
//Then to get it back:
uint8 value = theMap[index]
