Question

how to make a code with testcase like
input : 4a 3c 9o 0
output : aaaacccooooooooo0

input : 11b 3k 9
output : bbbbbbbbbbbkkk9

input : 4bab 18c 12g 7
output : babbabbabbabccccccccccccccccccgggggggggggg7

Answer 1

I guess you could start by splitting the input at its spaces. Then you could analyze every item, whether it has length 1 or not. If it's 1, simply print that char. If it's not 1, split this item into the last char and the rest. The last char is the one you want to print, and the rest of the string can be evaluated as an int. Loop this int number of times, and output the char, and finally a space.

Answer 2

try this

""""exception may arise if , input is not correct
"""
x=str(input("string :"))
t=x.split()
output=""
for i in t:
if i.isnumeric():
test=int(i)
output+=str(test)
else:
if (len(i)-2)==0:
y=str(int(i[0])*i[1])
else:
y = str(int(i[:(len(i)-1)]) * i[len(i)-1])
output+=y
print(output)

Answer 3

def get_part(input):
if len(input) <= 1:
return input
num=int(input.split(input[-1],2)[0])
return num*input[-1]

def get_line(input):
parts=[]
for i in input.split(" "):
parts.append(get_part(i))
return "".join(parts)

n=input()
inputs=[]
inputs.append(n)
for input in inputs:
print(get_line(input))

if i
input : 4bab 18c 12g
outout : bbbbccccccccccccccccccgggggggggggg

how to make it output is
babbabbabbabccccccccccccccccccgggggggggggg

Answer 4

@sharique

Answer 5

this shall be ultimate solution....just write gf4 instead of 4gf....

Hope this helps
