Answer:
"CoCoComputer Science"
Explanation:
First let's understand how the loop works, then we'll see what it does.
The variable i is initialized to value 0. Then inside the loop, it's incremented by 2 in each loop passage, while i < 8, so the loop will be processed with the following values of i: 0, 2, 4 and 6. It will run a total of 4 times.
Let's examine the actions done during the FIRST loop:
(str equals "Computer Science", so indexOf('m') = 2, i = 0)
- if the index of 'm' within the string is < i (index = 2, i = 0, FALSE)
does nothing
increases value of i by 2 (now i = 2)
Let's examine the actions done during the SECOND loop:
(str equals "Computer Science", so indexOf('m') = 2, i = 2)
- if the index of 'm' within the string is < i (index = 2, i = 2, FALSE)
does nothing
increases value of i by 2 (now i = 4)
Let's examine the actions done during the THIRD loop:
(str equals "Computer Science", so indexOf('m') = 2, i = 4)
- if the index of 'm' within the string is < i ( index = 2, i = 4, TRUE)
then str becomes "CoComputer Science"
increases value of i by 2 (now i = 6)
Let's examine the actions done during the FOURTH loop:
(str equals "CoComputer Science", so indexOf('m') = 4, i = 6)
- if the index of 'm' within the string is < i (index = 4, i = 6, TRUE)
then str becomes "CoCoComputer Science"
increases value of i by 2 (now i=8)
Loop ends because i = 8 (i < 8 becomes false)
