There is a string array r = [ABC, Bac, ACB]I only want to retain one of the strings, that is, to delete strings with the same content but different character combinations.
I will introduce you to the single-digit operation technique, which is limited to less than 32 letters.
Assume that the ASC code of the letter A is 97, then we subtract 97, so that the letter A-Z will be compiled from 0 to 25.A = 0; B = 1; C = 2; D = 3; E = 4; F = 5; G = 6 ....To

Question: enter a string to print all the characters in the string, such as the string ABC, all strings ABC, ACB, Bac, BCA, cab, and CBA that can be arranged by characters A, B, and C are output.
Analysis: This is a good programming question for understanding recursion, so it has frequently appeared in interviews and pen questions of major companies in the past year.

1. Use the next_permutation () function in STL (use n for n numbers! Then we can get its full sorting amount:
Boolean next_permutation (. begin (),. end () This function is constructed by the characters in the input string in alphabetical order to determine whether there is another string after the current string. If the number of next_permutation executions is less than the total number of characters in the string, returns true. For example, if a = "abc" is fully arranged w

Finally, I will share a simple, but equally interesting geometric proof question.:For example, to create an arbitrary Triangle ABC's incircle ⊙ I, it is tangent to AC at point N. Over N for the vertical line of AC, and another point of intersection with ⊙ I for M (So Mn is a diameter of this circle ). Connect and extend BM, and submit it to point L. Proof: Cn = Al.

| $ARGC" It is common practice to enter program parameters at the command line to change how they are run. You can also do this to the CLI program. The PHP CLI has two special variables that are specifically designed to achieve this purpose: one is$argvVariable, which saves the parameters passed to the PHP script as a separate array element through the command line, and the other is$ARGCVariable that is used to hold the number of elements in the $ARGV array.

From Wikipedia:
In mathematics, torle's theorem is a quadrilateral Theorem in Euclidean geometry. Torle's theorem indicates that the sum of the product of the two sides of a convex quadrilateral is not less than the product of the two diagonal lines. An equal sign is obtained only when the quadrilateral is a circular inner quadrilateral or degrades to a straight line (also known as Euler's theorem ). The narrow tolemi theorem can also be described as: the product of the two sides of a convex qu
1. Question:
Enter a string to print all characters in the string.
For example, if the input string ABC is used, all strings that can be sorted by characters A, B, and C are output.
ABC, ACB, Bac, BCA, cab, and CBA.
Solution:
Select each element from the set, and use it as the first element in the arrangement. Then, the remaining elements are arranged in full order. In this way, all elements are arranged recursively. Taking ABC as an example, we can d
