# Convert String into Binary Sequence

Given a string of character the task is to convert each character of a string into the equivalent binary number.

Examples :

```
Input : GFG
Output : 1000111 1000110 1000111

Input :  geeks
Output : 1100111 1100101 1100101 1101011 1110011
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

The idea is to first calculate the length of the string as n and then run a loop n times. In each iteration store ASCII value of character in variable val and then convert it into binary number and store result in array finally print the array in reverse order.
