There was only one question. How to compress a string? If "AAABBAAA" the resultant string should be 3A2B3A.
Write a program to find the square root of a double.
Write a function to search for a string within another string. Analyze it's complexity, and propose optimizations.
given an arrya of numbers see if you can get to index with 0 in it from an index by jumping through the array using the values in the array. So if you have [1,2,1,0,3] you can get to 0, from 0 by jumping 0, you can get to 0 from 3, by jumping 3 index down to 2 and then jumping 2 index up to 0...
Why Accenture?
Find the median of unsorted array in O(nlog n ) time. You need to know that particular mathematical algorithm, anything slower your answer is rejected.
(Phone screen questions) 1. For a given binary tree, print paths from root to all leaf nodes, one path per line. 2. Given a sequence of positive integers "seq" and an integer "total", return whether a contiguous sequence of "seq" sums up to "total". (Onsite interview questions are covered by NDA therefore can't post, but it can be said that the knowledge of data structures and handling edge cases are important for the coding interviews)
Given a collection of words, return a collection of anagrams found in the given collection
