Create Node.js controller

Create a Node.js Controller which have the following functionality: Convert the string S: S = "Magic=3\nMagic,F=1\nMagic,1=1\nMagic,2=2\nMagic,3=13\nMaxEAEquityDD=10\nMaxEAEquityDD,F=1\nMaxEAEquityDD,1=10\nMaxEAEquityDD,2=1\nMaxEAEquityDD,3=15" to this: Parameters : { { name: "Magic", value: "3", chequed: "1", start: "3", step: "2", end: "13", steps: {3,5,7,9,11,13} }, { name: "MaxEAEquityDD", value: "10", chequed: "1", start: "10", step: "4", end: "15", steps: {"10","14","15"} } } The String S could have n input parameters (not only Magic and MaxEAEquityDD). The values of each parameter are in a consecutive order (Magic=3 | Magic,F=1 | Magic,1=3 | Magic,2=2 | Magic,3=13) steps are created with the 3 values (start,step,end) - Start is the first value (in Magic is 3) - steps is the amount you have to add (in Magic 3 + 2 = 5) - end is the upper limit (in Magic is 13). Note that (value + last step) > end then the last value is end (for example in MaxEAEquityDD => (14 + 4) = 18 > 15), then last step is 15 = end
