在本文中,我们将讨论如何从一个只包含0和1字符的给定字符串中删除两个零之间的元素。最终的字符串不应包含任何被0包围的字符'1'。例如-
Input : string = “110010” Output : “11000” Explanation: 1 is found between two zeros at the 4th index. Input : string = “0010” Output : “000” Explanation : 1 is found between two zeros at the 2nd index.
We can apply a simple approach, i.e., traverse the string using a loop and check the previous and next elements whether they are zeros; if yes, then that index is not zero. After that, update the variable with a new length that stores length and print that string.
#include <bits/stdc++.h>
using namespace std;
int main () {
string str = "110010";
int length = str.length();
for (int i = 1; i < length - 1; i++) {
// checking the element between two zeros
if ((str.at (i - 1) == '0' && str.at (i + 1) == '0')) {
// deleting the element
// if it is found between two 0's
str.erase (i, 1);
i--;
if (i > 0 && str.at (i - 1) == '0')
i--;
// updating the length of the string after removing the element.
length = str.length ();
}
}
cout << "String after removing elements between the two zeros: " << str;
return 0;
}String after removing elements between the two zeros: 1100
在本文中,我们讨论了从包含'0'和'1'字符的字符串中删除两个零之间的元素。我们还看到了一个解决相同问题的C++程序;我们可以使用其他语言如C、Java、Python等编写这个程序。希望您觉得本文有帮助。
