to perform basic operations in an array or a string. By using these operations, we are able to solve some basic problems. However, it is obviously not enough. In this chapter, we are going to talk about the two-pointer technique which can help us with many array/string related problems!
Use two pointers with the first pointer ahead by N nodes.提示：使用两个指针，第一个指针领先 N ...
设两个pointer,left 和 right。 从最两边开始遍历,每一次都计算面积,比max大的话就替换。接着把低的那根线的pointer 向另外一边移动,直到两个pointers 相遇。 Java Solution: Runtime beats 31.31% 完成日期:07/11/2017 关键词:Array 关键点:Two Pointers 1publicclassSolution2{3publicintmaxArea(int[] height...
Two questions use the same idea, recursion and backtracking, when target hit 0, record the result. The combination sum allows unlimited duplicates while the other limits the duplicates numbers. Notice we always need to avoid duplicates by counting the number of same elements in the recursion for...

几道典型two pointers一快一慢题。记住j要匀速的走,i指向最终想要的数组的最后一个元素(或者倒数第二个,或者第一个可以被change的。。因题而异)。做的挺焦躁的,记下来对比练习: 1. Remove Elements:一个数组,删掉所有出现的x,返回新长度。 两个pointer,一个正常走,一个指向真正去掉x的数组的长度。
Use two pointers to create a window of letters in s, which would have all the characters from t. 提示2 Expand the right pointer until all the characters of t are covered. 提示3 Once all the characters are covered, move the left pointer and ensure that all the characters are still cove...
1.Two Pointers(Arrays, Strings,Fast & Slow Pointer) This pattern covers a huge set of questions related to Arrays and Strings, which are the highest tagged data structures. Fast & Slow Pointer can be easily understood as a variation of the Two Pointers pattern. ...
