不做任何转换打印一个数字的所有子串
给定一个整数 N,任务是打印 N 的所有子字符串,而不做任何转换,即将其转换为字符串或数组。
示例:
输入 : N = 12345 输出:可能的子串:{1,12,123,1234,12345,2,23,234,2345,3,34,345,4,45,5} 输入 : N = 123 输出:可能的子串:{1,12,123,2,23,3
进场:
- 根据大小取 10 的幂。
- 将数字除以 0,然后打印出来。
- 然后通过取 k 的模,将该数改变到该数的下一个位置。
- 更新位数。
- 重复同样的过程,直到 n 变成 0。
以下是上述方法的实现:
C++
// C++ implementation of above approach
#include <bits/stdc++.h>
using namespace std;
// Function to print the substrings of a number
void printSubstrings(int n)
{
// Calculate the total number of digits
int s = log10(n);
// 0.5 has been added because of it will
// return double value like 99.556
int d = (int)(pow(10, s) + 0.5);
int k = d;
while (n) {
// Print all the numbers from
// starting position
while (d) {
cout << n / d << endl;
d = d / 10;
}
// Update the no.
n = n % k;
// Update the no.of digits
k = k / 10;
d = k;
}
}
// Driver code
int main()
{
int n = 123;
printSubstrings(n);
return 0;
}
