2. Count a Specific Character in a String Using count() Method You can count the occurrences of a specific character in the string using thecount()method. For instance, first, initialize a string variable named

sep − Optional. Character dividing the string into split groups; default is space. maxsplit − Optional. Number of splits to do; default is -1 which splits all the items. str.rsplit([sep[, maxsplit]]) Thestr.rsplitreturns a list of the words in the string, separated by the de...
You can use thecount()method to count the number of occurrences of a specific character. In this case, the characterewithin the given string. In the below example, first, you can initialize a stringmystringwith the value"Welcome to sparkbyexamples". You can apply the count() method over ...
Lastly, an important application of strings is thesplitmethod, which returns a list of all the words in the initial string and it automatically splits by any white space. It can optionally take a parameter and split the strings by another character, like a comma or a dot ...

流程: 从count数组的第二个元素开始遍历。对于每个位置i,执行count[i] = count[i] + count[i-1]。遍历结束后,count[i]的含义变成了:小于或等于值为i + min(A)的元素在A中的总数量。这个值,恰好就是值为i + min(A)的元素在最终排好序的数组中,应该放置的最后一个位置的索引(从1开始计数)。
