reverse integer in python

In this post, you learned how to reverse a number using both math and string indexing. python - Reversing an integer without using reverse functions or lists Daftar Situs Slot Gacor Terbaru 2022 Terpercaya Gampang Menang Maxwin Hari Ini. In each case we will check whether the number is in range of 32-bit integers. (You might want to round up to the nearest multiple of 8). You expect that 0x1 will be translated to 0x80 (0b00000001 -> 0b10000000). You can cast an integer to string with str(i) and then use your reverse function. example: input 36800 //int num=36800 after reverisng //num=reverse(str(num)) output 863 *****but I need to get 00863 Why last zero's are trimmed Can i know the reason. Thus, we can use the mathematical approach to check if a number is a palindrome. Thanks for contributing an answer to Stack Overflow!
