Interpolation Search. Youtube. GFS. The search works well for uniformly distributed numbers. Formula Calculation - So the formula to estimate the position = pos = lo + [ (x-arr[lo])*(hi-lo) / (arr[hi]-arr[Lo]) ] arr[] ==> Array where elements need to be searched x ==> Element to be searched lo ==> Starting index in arr[] hi ==>… Continue reading Searching Problem List

## Array – Java

Very basic way to use java array - You can either use array declaration or array literal (but only when you declare and affect the variable right away, array literals cannot be used for re-assigning an array).For primitive types: int[] myIntArray = new int[3]; int[] myIntArray = {1,2,3}; int[] myIntArray = new int[]{1,2,3}; For classes,… Continue reading Array – Java
