Why such vast execution-time difference in the two solutions?
I was solving "Digit sum" problem of Atcoder dp contest. I am just curious why my two solutions have such a vast difference in their execution time. 
My First solution which took more than 2000ms (https://atcoder.jp/contests/dp/submissions/24396061)
My Second solution which took less than 200ms (https://atcoder.jp/contests/dp/submissions/24396078) 
Just adding some more parameters to a function completely changed the time complexity, strange isn't it?
