Deduction

I was solving maximum subarray question when I found a useful explanation to break down and deduce ternary operator.

public int maxSubArray(int[] nums) {
    int n = nums.length;
    int[] dp = new int[n];
    dp[0] = nums[0];
    int max = dp[0];
    for(int i=1;i<nums.length;i++){
        //this is deduction of ternary operator
        // dp[i] = Math.max(nums[i]+dp[i-1], nums[i]);
        // dp[i] = nums[i] + Math.max(dp[i-1],0)
        dp[i] = nums[i] + (dp[i-1]>0 ? dp[i-1] : 0);
        max = Math.max(max,dp[i]);
    }
    return max;
}

The first commented runs just fine but this ternary operator looks much cleaner.
