The wsq10 asks me to do a program that recieves only two data from the user: a lower bound and an upper bound.<\/p>\n

With thopse two parameters I had to tell the user how many palindromes, see for palindromes<\/a><\/span>, are in that range; how many palindromes are in that range after do the\u00a0Lychrel number test and how many Lycher there exists, see for Lychrel<\/a><\/span>.<\/p>\n

The first thing I did was seting the condition needed to get a natural palindrome, like 55 or 101, then to set a condition to exclude base 10 numbers, like 130 o 18290;<\/p>\n

<\/a><\/p>\n

That means, if x and y are the same (if is a palindrome \ud83d\ude42\u00a0) we’ve got a palindrome; <\/em>if the last digit is cero, then is a base 10 number and i counted it as a plaindrome.<\/p>\n

Then, the hard parts makes its entrance<\/p>\n

<\/a><\/p>\n

Well, that means that if it is not a natural palindrome, and is not a base ten number, then we will try to convert it to palindrome by adding the number with its inverse, in the code is the part x = x + y, where y = x[::-1].<\/p>\n

EXTRA: the code x[::-1] means that it will ignore the start and the end and it just going to move the last digit. The wrong way to do it it’s putting cero<\/p>\n

So that loop will check it 30 times, if it does not meet the condition x == y, then it will be a Lychrel number, else it will be a forced palindrome.<\/p>\n

It was really a challange to me and I really liked it; i’d like to do more of those challenging programs<\/p>\n
