Product of array except self

Ayush Pandey solution

public int[] productExceptSelf(int[] nums) {
        int l = 1;
        int[] res = new int[nums.length];
        res[0] = 1;
        
        for(int i = 1 ;i< nums.length ;i++){
            res[i] = res[i-1]* nums[i-1];
        }
        int right = 1;
        for(int j =  nums.length-1 ; j>=0;j--){
            res[j] = right * res[j];
            right *= nums[j];               
                //1 1 2 6
                //
                //24 12 8 6
        }
        return res;
