Recurring Sequence In A Fraction

hard

1. You are given two numbers which represent the numerator and denominator of a fraction. 2. You have to convert this fraction into a decimal. 3. If the decimals are repeating recursively, then you have to put the recurring sequence inside a bracket.

Constraints

1 <= N1,N2 <= 2000

Format

Input

A number N1 representing the numerator of a fraction. A number N2 representing the denominator of a fraction.

Output

A String representing a decimal number.

Example

Sample Input

```.css-23h8hz{color:inherit;font-size:0.875rem;line-height:1.125rem;letter-spacing:0.016rem;font-weight:var(--chakra-fontWeights-normal);white-space:pre-wrap;}8 4```

Sample Output

```.css-3oaykw{color:var(--chakra-colors-active-primary);font-size:0.875rem;line-height:1.125rem;letter-spacing:0.016rem;font-weight:var(--chakra-fontWeights-normal);white-space:pre-wrap;font-family:Monospace;}2 ```
