Merge the Tools!

Tip

• We can solve this problem with set
• However, better way, is the using string replacement
• Substring as per the length of k
• input is s
• pick the first character, and replace it to ''
• s.replace(s[0])
• Now, duplication of first character is resolve
• To apply the way, to whole string, please see below
• s[0:j] + s1[j:].replace(s1[j-1], '')

Solution

def merge_the_tools(s, k): # your code goes here for i in range(len(s)): s1 = s[i*k:(i+1)*k] j = 1 while j < len(s1): s1 = s1[0:j] + s1[j:].replace(s1[j-1], '') j += 1 print(s1) if __name__ == '__main__': string, k = input(), int(input()) merge_the_tools(string, k)
