# Problem 53750. Easy Sequences 63: Base-63 Arithmetic Functions

In this exercise we are required to implement 7 basic 'unsigned integer' arithmetic functions in base-63:
• to63(x) - converts an integer from base-10 to base-63.
• to10(x) - converts an integer from base-63 to base-10.
• add(x,y) - adds two base-63 integers.
• sub(x,y) - subtracts two base-63 integers.
• mul(x,y) - multiplies two base-63 integers.
• div(x,y) - performs integer division between two base-63 integers.
• mod(x,y) - returns the remainder of division between two base-63 integers.
NOTES:
• All outputs shall be char-string format.
• Except for the function 'to63' (which may input numbers), all inputs shall be in char-string format.
• Use the numerals '0' to '9' for digits 0 to 9, capital letters 'A' to 'Z' for digits 10 to 35, lower case letters 'a' to 'z' for digits 36 to 61 and the symbol '_' (underscore) for digit 62.
