Write a Java program to find the index of the first unique character in a given string. Assume that there is at least one unique character in the string. Pictorial Presentation: Sample Solution: Java Code: importjava.util.*;publicclassSolution{publicstaticvoidmain(String[]args){// Test the ...
#include <iostream> #include <memory> #include <string> int main() { std::shared_ptr<int> sp0; std::shared_ptr<std::string> sp1; sp1.reset(new std::string()); std::unique_ptr<int> sp2; std::weak_ptr<int> sp3; std::cout << "sp0 size: " << sizeof(sp0) << std::endl;...
Given a string, find the first non-repeating character in it and return it's index. If it doesn't exist, return -1. 给一个字符串,返回第一个不重复的字符的index,要是没有的话就返回-1 //第一次做,感觉巨简单,设一个set,一旦contains,就用striing.indexOf()---还能用上不熟悉的函数,简直完...
Given a string, find the first non-repeating character in it and return it's index. If it doesn't exist, return -1. Examples: s = "leetcode" return 0. s = "loveleetcode", return 2. 解题思路: 开个26个数的数组,然后先对字符串过一遍,统计每个字母出现的次数,然后从头再国一遍,第一个...
In the below example, we will illustrate how we can find the unique values from the list using the methoddistinct(). The example code is shown below: // importing necessary packagesimportjava.util.*;importjava.util.stream.Collectors;publicclassUniqueList{publicstaticvoidmain(String[]args){// ...
// Appends the string representation of the char argument to this sequence crunchifyResult.append(crunchifyKeys[(myByte & 0xf0) >> 9]); crunchifyResult.append(crunchifyKeys[myByte & 0x0f]); } return crunchifyResult; } } Output: Just run above program as a Java Application and you w...
Error in make.names(col.names, unique = TRUE) : invalid multibyte string 1,程序员大本营,技术文章内容聚合第一站。
The most straightforward way to find the number of unique digits in an integer is by using aSet. Sets inherently eliminate duplicates, which makes them perfect for our use case: Let’s break down our algorithm’s steps: Convert the integer into a string to easily iterate over each digit. ...
String format is URL safe and has no hyphens. For the story of how KSUIDs came about, seeA brief history of the UUID. Usage as cli To use this as a command-line program on Unix-like systems, run wget https://repo1.maven.org/maven2/com/github/ksuid/ksuid/1.1.3/ksuid-1.1.3-cl...
2. Find Distinct Elements in a Stream of Strings or Primitives It is easy to find distinct items from a list of simple types such asStringandwrapper classes. These classes implement the requiredequals()method, which compares the value stored in it. ...
