https://ide.codingblocks.com/s/136280 Another code where I used Sting.format("%05d,ans) to print leading zeroes but this prints only 5 digits .How can I print Digits in answer equal to the number of digits in input

The length of number is upto 100 in question … you have used int . Int can store only upto length 7 … use string for this .

#5

Further XOR uses the following principle in which it converts decimal to binary and then solves and then return answer as decimal again .So the decimal will not have front zeroes
