We will split the string into two halves, one before index i and the other after index i. Then we can join these two strings to get the string that will not have the i-th character. To split the string we will use the concept of slicing. Slicing specifies how to slice a sequence into smaller objects where the starting and ending index is specified by us.
We have sliced the string into two substrings and stored each substring in another variable then we have joined the two substrings using the concatenation operator (+). Since, indexing in a string starts with 0, to remove i-th character, we have to pass i-1 as an index in our function.
