#3

yes, i understood question but could not think about the logic to solve ths

#4

iterate over array and check if current element is greater or smaller than previous element

case1 : if it is greater means sequence is increasing here now for next time it can’t be decreasing
case2: if it is smaller than previous then it should not increasing before it

if these condition not hold true ans is “false” otherwise “true”
