Design an *O(n)*-time algorithm that, given a real number *x * and a sorted array *S* of *n * numbers, determines whether or not there exist two elements in *S* whose sum is exactly *x *.
since array is already sorted, doing binary search for x-S[i] ,for each element indexed at i will give a nlogn solution. How to get O(n) solution?? -- Harshal Choudhary -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
