# Program to find minimum distance to the target element using Python

Suppose we have an array nums and two different values target (target must present in nums) and start, we have to find an index i such that nums[i] = target and |i - start| is minimum. We have to return the |i - start|.

So, if the input is like nums = [3,4,5,6,7] target = 7 start = 2, then the output will be 2 because there is only one value that matches with target, that is nums[4], so i = 4. Now |4-2| = 2.

To solve this, we will follow these steps:

minimum := infinity

for i in range 0 to size of nums, do

if nums[i] is same as target, then

if |i - start| < minimum, then

minimum := |i - start|

return minimum

Let us see the following implementation to get better understanding −

## Example

from math import inf def solve(nums, target, start): minimum = inf for i in range(len(nums)): if nums[i] == target: if abs(i - start) < minimum: minimum = abs(i - start) return minimum nums = [3,4,5,6,7] target = 7 start = 2 print(solve(nums, target, start))

## Input

[3,4,5,6,7], 7, 2

## Output

2
