Q1
The following pseudocode is executed using the Words dataset. `explode(X.Word)` returns the list of letters in `X.Word`. For example, `explode("apple")` returns `["a", "p", "p", "l", "e"]`. `isVowel(c)` returns `True` if `c` is a vowel, and `isConsonant(c)` returns `True` if `c` is a consonant. What will `cnt` represent at the end of execution?
```
cnt = 0
while(Table 1 has more rows){
Read the first row X in Table 1
letters = explode(X.Word)
if(checkPattern(letters)){
cnt = cnt + 1
}
Move X to Table 2
}
Procedure checkPattern(S)
if(length(S) < 2){
return(False)
}
prev = first(S)
res = rest(S)
foreach curr in res{
if(isVowel(prev) and isConsonant(curr)){
return(True)
}
prev = curr
}
return(False)
End checkPattern
```

Q2
Consider the following pseudocode. If at the end of execution, , then choose the correct code for procedure `checkCondition`.
```
A = [3, 8, 15, 6, 10, 5]
B = []
foreach number in A {
if(checkCondition(number)) {
B = B ++ [number]
}
}
```

Q3
Consider the following pseudocode. The `floor(n)` function returns the largest integer value smaller than or equal to `n`. The `remainder(x, j)` function returns the remainder when `x` is divided by `j`. What will the value of `B` be at the end of execution?
```
A = [18, 19, 24, 21, 13]
B = []
foreach number in A {
if (checkCondition(number)) {
B = B ++ [number]
}
}
Procedure checkCondition(X)
sum_of_digits = 0
temp = X
while (temp > 0) {
digit = remainder(temp, 10)
sum_of_digits = sum_of_digits + digit
temp = floor(temp / 10)
}
if (remainder(X, sum_of_digits) == 0) {
return(True)
}
else {
return(False)
}
End checkCondition
```

Q4
Consider the following pseudocode. What will the value of `B` be at the end of execution?
```
A = [3, 8, 15, 6, 10, 5]
B = []
foreach number in A {
if (checkCondition(number)) {
B = B ++ [number]
}
}
Procedure checkCondition(X)
if (X == 1) {
return(False)
}
j = 2
flag = True
while (j < X) {
if (remainder(X, j) == 0) {
flag = False
}
j = j + 1
}
return(flag)
End checkCondition
```
