Python: Restore the original string by entering the compressed string with specified rule
Python Basic - 1: Exercise-58 with Solution
When character are consecutive in a string , it is possible to shorten the character string by replacing the character with a certain rule. For example, in the case of the character string YYYYY, if it is expressed as # 5 Y, it is compressed by one character.
Write a Python program to restore the original string by entering the compressed string with this rule. However, the # character does not appear in the restored character string.
Note: The original sentences are uppercase letters, lowercase letters, numbers, symbols, less than 100 letters, and consecutive letters are not more than 9 letters.
Input:
The restored character string for each character on one line.
Original text: XY#6Z1#4023
XYZZZZZZ1000023
Original text: #39+1=1#30
999+1=1000
Sample Solution:
Python Code:
def restore_original_str(a1):
result = ""
ind = 0
end = len(a1)
while ind < end:
if a1[ind] == "#":
result += a1[ind + 2] * int(a1[ind + 1])
ind += 3
else:
result += a1[ind]
ind += 1
return result
print("Original text:","XY#6Z1#4023")
print(restore_original_str("XY#6Z1#4023"))
print("Original text:","#39+1=1#30")
print(restore_original_str("#39+1=1#30"))
Sample Output:
Original text: XY#6Z1#4023 XYZZZZZZ1000023 Original text: #39+1=1#30 999+1=1000
