function solution (data, replace) {
  //Replace all values of "dynamic" with replace
  if (data == null)
  return data;

  for (var prop in data)
    if (data.hasOwnProperty(prop)) {
        if (data[prop] == "dynamic")
        data[prop] = replace;
    }
    if(data[prop] instanceof Object || data[prop] instanceof Array) {
        var  result = solution(data[prop], replace);
    } 
    console.log(data);
  
  
  return data;
