datastructure Validity - integer Value - Whatever Make an array of the above datastruct (say d[n+1] starting from 1) integer maxcount
Init(val) d[n+1].Value = val d[n+1].Validity = ++maxcount Set(i,x) d[i].Value=x d[i].Validity = d[n+1].Validity+1 Get(i) if( d[i].Validity <= d[n+1].Validity ) then d[n+1].Value else d[i].Value There is a practical issue that Validity may become larger than int etc... however that too can be easily overcome. -------------------------------------------------- Rohit Saraf Third Year Undergraduate, Dept. of Computer Science and Engineering IIT Bombay http://www.cse.iitb.ac.in/~rohitfeb14 -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
