#Quick word search algorithms code#
This is a good c++ sample code to observe binary search written by me. Maxx = midd // our midd must be lower to reach x, that is why we should decrease midd Int x // the number which we are looking for This means that the average number of guesses to find an element is the same, regardless of whether we round up or round down. However, if we performed a series of binary searches to find every element, one by one,and took the grand total of the number of guesses from all of these searches, the grand total would be the same regardless of whether we round up or down. The number of guesses required to find a particular element will be different depending on whether we round up or round down. No length information is provided if needed, it must be computed. (the rounding determines whether the smaller chunk will be above or below the guess)Īfter we look at the value of our guess we will be able to eliminate the elements above or below our guess. Needle (pattern) and haystack (text to search) are both C-style null-terminated strings. If the number of elements remaining are even then we will have n/2 elements on one side of the guess and n/2-1 elements on the other side, regardless of whether we round up or down. If the number of elements remaining are odd then we will have (n-1)/2 element above and below our guess. Function should return a pointer to the first match, or NULL if no match is found.
What is important is the number of elements to either side of the guess. Needle (pattern) and haystack (text to search) are both C-style null-terminated strings.
