What is the algorithm to reverse all the digits of an integer?
To reverse all the digits of an integer, you can use the following algorithm: Initialize a variable to store the reversed number. While the original number is greater than zero, extract the last digit using the modulus operator (%), append it to the reversed number by multiplying the current reversed number by 10 and adding the extracted digit. Then, remove the last digit from the original number by performing integer division by 10. Finally, handle any potential negative signs if needed.
The sum of the digits in a two digit number is 9 if the digits are reversed the new number will be 9 less than the original?
78 Good guess, but 7 + 8 = 15, not 9; so that answer is incorrect. The correct answer is 54. 5 + 4 = 9 45 is 9 less than 54. * * * * * If the sum of the digits of a 2-digit number is 9, and if the order of the digits is reversed the new number will be a multiple of 9 different from the original. It could be bigger or smaller, and the difference could be 18 or 27. For example, 7+2 = 9 and 72 -27 = 45 (which is not 9 but a multiple of 9)
The sum of the digits in a two digit number is 9 If the digits are reversed the new number will be 9 less than the original number What is the original number?
Possibility of two digit no whose sum is 9 18,27,36,45,54,63,72,81 Subract 9 with each no mentioned above output is 9,18,27,36,45,54,63,72 See after 4th comma 54 and 45. Reverse 54=45. now 45 is 9 less than 54. So the original no is 54

The sum of the digits in a two digit number is 10 If the digits are reversed the new number will be 72 more than the original number What is the original number?
Possibility of two digit no whose sum is 10 Are 19,28,37,46,55,64,73,82,91 Add 72 to each no mentioned above output is 91,100,109,118,127,136,145,154,163 See first 19 and 91 Assume that two digit no as 19 reverse it 91 will come. The no 92 is 72 more than 19 So 19 is the original

How many 2 digits numbers are such that the difference of the number and the number with the digits reversed is a perfect square?
If the number with the digits reversed can have a leading 0 so that it is a 1-digit number, then 16. Otherwise 13.
